Don’t Skip Out on Antivirus Software in 2023
Protect your PC from nasty viruses this flu season. Here’s what’s best for malware protection and more.
You might think you’re smart enough to avoid viruses, but even the smartest of tech aficionados can get fooled — yes, even us. That’s why it’s so important to invest in an antivirus software that can efficiently protect your system. These programs can help protect not only your devices, but your information as well, which hackers, scammers and other internet bandits would love to get their hands on. These rascals are getting smarter every day, developing new techniques and methods all the time. Fortunately, there are tons of great antivirus softwares available in 2023, so you’ve got plenty of options to keep your computer safe. We’ve put some of the most popular softwares out there to the test to bring you the best antivirus software options out there.
Windows devices make up three out of every four laptop or desktop operating systems, according to the latest data from Statcounter. Windows-targeted malware has a larger base of devices to infect, giving it more potential in the eyes of cybercriminals.
We’re here to help you find the antivirus software that best fits your needs. These picks of the best antivirus programs are a combination of recommendations from independent third-party labs AV-Test, AV-Comparatives and SE Labs, as well as CNET’s own hands-on testing. We regularly research and test software to determine which product leads the pack, and we update this list periodically based on those tests.
Note that antivirus software is only one piece of the cybersecurity puzzle. Cybercriminals are becoming more sophisticated, and the more steps you take to lock down your online security, the safer you’ll be. A secure virtual private network can help protect your internet privacy, and a password manager will help you create and keep track of more secure login credentials. These tools are all essential in protecting your personal information.
Our recommendations
Whether you’re looking for free antivirus protection or are willing to pay for a program that offers more security features, we have you covered. Here’s where to start when looking for the best antivirus software for your specific needs.
Note: The pricing structure for antivirus services can be complicated, since providers often offer low introductory prices to entice you to sign up for their services. After the first billing period — typically a year or two, depending on the plan you purchase — the amount you pay for the service may increase substantially. The regular rate for the services may be double the introductory rate or sometimes more. Be sure to check the terms of the subscription plan prior to making your purchase so you don’t get an unwelcome surprise when your subscription renews.
Also worth considering
In addition to the four antivirus apps we recommend above, a handful of other anti-malware tools are worth considering among the best antivirus protection if you find them at a better price or just prefer to use one over our picks above.
What about Avast?
Test after test, Avast Antivirus for Windows performs well for malware detection with options ranging from Avast free antivirus software to Avast Premium Security. And we’ve included its antivirus in our list of recommended security app options before. But Avast was in the news for several months for its non-antivirus business, so we looked at the company, specifically reports at the end of 2019 that Avast allegedly collected user data with its browser plug-ins and antivirus software and then sold data it collected through its Jumpshot subsidiary in early 2020.
In response to the reports that his company gathered and sold the details of its customers’ online activities, Avast CEO Ondrej Vlcek said in a statement that he understood that his company’s actions raised questions of trust in his company. To address that, Avast terminated Jumpshot data collection in January 2020 and closed its operations because the data collection business wasn’t in line with Avast’s privacy priorities.
Those reports followed another in 2019 from Avast that its internal network was breached, possibly to insert malware into its CCleaner software, similar to an earlier CCleaner hack that occurred prior to Avast’s acquiring the Windows utility.
Avast started saying the right things about taking its customers’ privacy seriously, but it only came to that point after reacting to investigative reporting that revealed the Jumpshot practices. (The CCleaner revelations, while concerning, were self-disclosed, which is important to building user trust.) We hope Avast’s more privacy-friendly policies mean that there will be no further Jumpshot-style activities and that it returns to glory as one of the best antivirus software options. In the meantime, we’d recommend using one of the many other solid choices in this realm (listed above).
What about Kaspersky?
Because the company has been in the news the past few years, let’s talk about Kaspersky Lab — specifically about the federal ban that blocks US government agencies from using Kaspersky Antivirusproducts.
Based in Moscow, Kaspersky Lab has for years produced some of the best antivirus software for business antivirus needs and home customers. But in 2017 the US government prohibited Kaspersky security cloud software on federal government computers because of alleged ties between Kaspersky and the Russian government.
Notably, the ban does not apply to its consumer products such as Kaspersky Total Security and Kaspersky Anti-Virus. But as with China-based Huawei, the question remains: If the federal government doesn’t think the products are safe enough for its own devices, should consumers avoid them as well?
In a statement sent to CNET, the company said, “Kaspersky Lab has no ties to any government, and the company has never, nor will ever, engage in cyber offensive activities. Kaspersky Lab maintains that no public evidence of any wrongdoing has been presented by the US government, and that the US government’s actions against Kaspersky Lab were unconstitutional.”
In Kaspersky’s favor, it continues to earn top scores and awards for virus and malware detection and endpoint protection from independent testing labs. And it’s reasonably priced.
In the end, even though no one has ever publicly produced a “smoking gun” linking the company to Russian intrigue, we think any of the options listed above is a safer bet. And if you are a US government employee or work with the federal government, you’ll want to steer clear of Kaspersky internet security products — and perhaps use one of the antivirus software products mentioned here instead.
Antivirus basics: What to look for
Picking the best antivirus software for Windows means finding one that keeps your PC safe, doesn’t take up a lot of system resources, is easy to use and stays out of the way till you need it. Here’s what to look for.
Effectiveness. Antivirus software runs virus scans for known viruses and malware, of course, and can offer real-time protection. And it watches for shady websites and suspicious links to keep you out of trouble. It can also offer ransomware protection and monitor unexpected behavior that may be a sign of new and not-yet-identified viruses and malware. You want antivirus software that can successfully identify these unknown online threats without flagging too many false positives.
Light on system resources. You don’t want antivirus software that taxes your PC’s resources. If after you install the program, websites open slowly, apps download or open sluggishly or file copies take longer than expected, you may want to try another service. The good news is, all our picks offer a free trial or money-back guarantee to let you try out the antivirus program, so if your system feels sluggish after installation, you may want to keep looking.
Cost and discounts. Don’t just pay the sticker price for antivirus protection. Before you buy, check for discounts on a company’s website. Another way to save: The prices we list above are for 10 devices — if the company offered that package — but you can trim your cost with antivirus packages if you need to cover three or five devices. You may also find discounts on an app’s Amazon page.
Privacy. To be effective, antivirus software needs to monitor what’s going on with your PC, check in with company servers about unusual behavior and should provide sound banking protection. The companies say they anonymize this technical data as much as possible to protect your privacy. But if you want to know more, the security companies on our list post privacy policies on their websites, so read their privacy statements to learn what the companies do with the information you share.
Protection for other platforms. Microsoft is by far the biggest target for viruses and malware. But Android is second, with just under 1% of apps installed on Android devices with Google Play Protect in the potentiallyharmful app, or PHA, category.
The threat to MacOS and especially iOS is low, in part because of the tight control Apple has over its app stores. While the Mac does come under attack via side-loaded apps, it’s rare, and if you download apps only from the Mac and iOS app stores and keep your guard up when clicking links and download files, you should be OK without an antivirus app on Apple devices.
Antivirus FAQs
Can antivirus protect against phishing?
To a degree, yes. Some antivirus programs can do things like warn you or block you from visiting a suspected phishing site. Others may also automatically block suspicious emails that appear to come from a malicious sender or contain phrasing common in phishing emails. However, you cannot count on an antivirus program to be a failsafe solution for phishing protection. You still need to be vigilant and know what to look out for on your own when it comes to phishing, because an antivirus program won’t be able to catch everything.
Will antivirus slow down my computer?
Any program running on your computer will require a certain amount of processing power to work, which can affect your computer’s overall performance. If an antivirus program is just running in the background, it shouldn’t really have any effect on your computer’s performance. However, when actively running a scan of your system, an antivirus can noticeably slow down your computer. If this is the case, try to schedule antivirus scans at night, or at a time when you’re not using your computer.

Chinaâs super-rich fled Singapore. Now they want to come back
Wealthy Chinese are reconsidering Singapore as Beijingâs offshore wealth scrutiny and geopolitical risks make alternatives less attractive.
A year ago, wealthy Chinese families were souring on Singapore. Its rules felt onerous, its nightlife subdued. Other cities seemed easier or more exciting.
Now they want to come back.
Family-office advisers and wealth managers say they are seeing renewed interest in Singapore from affluent Chinese clients who had shifted their lives to other financial centers, as tightening scrutiny from Beijing and geopolitical turmoil make its stability look attractive again.
The reversal underscores how quickly the calculations of Asiaâs wealthy can change.
Singapore emerged as a favored destination for wealthy mainland Chinese seeking to diversify their assets and gain distance from Beijing, particularly after Hong Kongâs 2019 protests and subsequent national security crackdown.
However, its appeal faded after a $3 billion money-laundering scandal in 2023 triggered tighter scrutiny of wealthy clients and family offices. Stricter compliance checks, lengthy bank onboarding and residency requirements pushed some Chinese families toward jurisdictions they viewed as easier or more appealing – such as Hong Kong, Dubai and Tokyo.
Theyâre now telling me I really want to come to Singapore to become a citizen.Ryan LinBayfront Law
But what once seemed restrictive is increasingly being viewed by some as a source of security.
âThe very reason why they came to Singapore in the first place back then was because Chinaâs policies impact Hong Kong much closer to them than in Singapore,â said Bayfront Law director Ryan Lin.
Lin, who advises wealthy Chinese clients on setting up family offices and securing residency in Singapore, said last year that he was increasingly helping clients move away from the city-state as tighter compliance and disclosure requirements eroded its appeal.
The shift comes as Beijing steps up scrutiny of wealth held outside mainland China. New rules affecting offshore trusts have rattled wealthy families because of requirements to disclose structures and potential tax liabilities, while tighter oversight has also extended to areas including insurance and offshore brokerage accounts. These rules can apply regardless of where a trust is located or where an individual physically lives.
âWhen it comes to the safety of their wealth, they probably now are considering Singapore very, very seriously for the long term,â he said, adding that they are more determined this time, with several asking about pathways to permanent residency and citizenship as they consider making Singapore a longer-term base.
Moving to Singapore does not automatically sever an individualâs obligations to China, said Carman Chan, founder of Hong Kong and Singapore-based family office Click Ventures, particularly without a change in citizenship or tax status.
Advisers say the renewed interest in Singapore is generally about creating physical, financial and political distance from the mainland while maintaining additional options.
Lin said recent restrictions affecting mainland investorsâ access to offshore brokerages in Hong Kong had particularly unsettled some clients. âThey find perhaps Hong Kong is really too close to China,â he said.
Manish Tibrewal, co-founder of family office Farro Capital, said his firm has seen a sharp pickup in inquiries from Chinese families considering to relocate to Singapore.
A spokesperson for Hong Kongâs Financial Services and the Treasury Bureau said that under the âone country, two systemsâ framework, âHong Kong upholds the common law system, the free flow of capital, the free convertibility of its currency, a simple and low tax regime, and a regulatory framework aligned with international standards.â
Dubai reversal
Singapore is also benefiting from a different source of anxiety: the Middle East.
Several advisers, including Tibrewal and Lin, said Chinese families who shifted toward Dubai in recent years have reconsidered their plans amid conflict in the region.
Lin said some of his clients initially treated the conflict as a temporary shock. But as tensions persisted, families began taking more concrete steps to leave.
âMy clients are afraid that Dubai may potentially be easy collateral damage.â Lin said. âTheir sense of security will not be there. They will be frantic. At least mentally, they wonât feel very safe. Their mindset of managing money in Dubai has changed.â
Some have already returned while others are unwinding investments and financial arrangements before doing so, he said.
Japanâs barriers
Tokyo had become attractive to wealthy Chinese in recent years as a weak yen made everything from property to luxury goods cheaper. Its proximity to China and safety had also made it an obvious alternative to Singapore.
Yet language barriers, difficulties integrating into Japanese society and differences in business and social culture caused issues, advisers said.
Iris Xu, CEO of Jenga Business Consulting Group, a consultancy that works with wealthy families, cited one client who relocated to Japan but returned to Singapore after just eight months.
âAfter going to Japan, going to Dubai, going to Hong Kong, there remains the Singapore option,â Xu said.
Back to Singapore
The renewed interest also arrives as Singapore itself fine-tunes the rules governing its family-office industry.
The Monetary Authority of Singapore in July eased some conditions for single-family offices seeking tax incentives, with the changes taking effect Aug. 1. The revisions give offices greater flexibility on hiring and investment requirements even as authorities continue to strengthen checks on the sources of wealth entering the country.
âWealth owners from a diverse range of countries choose Singapore for many reasons, including our high standards of regulation, strong rule of law, and a comprehensive ecosystem of wealth managers and professional service providers,â an MAS spokesperson told CNBC.
Advisers for the wealthy say Singaporeâs advantage is increasingly the predictability that comes with its rules.
âTheir priorities have changed,â Xu said. âBefore, maybe they were looking for an opportunity. Now they are looking at safety.â

U.S.-Iran escalation shows Washington’s frustration with slow-moving sanctions
Renewed hostilities reopen the question of whether the conflict is grinding toward a settlement or further escalation.
The escalation in hostilities between the U.S. and Iran over the weekend shows the U.S. is running out of patience with the slower-moving sanctions approach, according to analysts.
U.S. forces destroyed two Iranian rocket launchers on Larak Island on Sunday, as the Islamic Republic prepared to fire mine-carrying rockets into the Strait of Hormuz, ending a month-long lull in direct fighting.
The strike was the first publicly acknowledged U.S. attack since late July. Iran responded within hours, firing eight missiles at the King Hussein and Al Azraq air bases in Jordan. Jordanian air defenses intercepted all eight, with no casualties, the government said.
Later Sunday, President Donald Trump threatened on social media to blow up Kharg Island, Iranâs main oil-export hub, to âsmithereens.â
âMost of the war has been tactically focused rather than strategic from the outset,â said Ian Ralby, a maritime security expert and president of Auxilium Worldwide. âThe question, therefore, is: why this, why now?â
The sanctions campaign may not be hurting Iranâs leadership fast enough for the U.S.âs liking, Ralby said. Treasury Secretary Scott Bessent told Reuters on Sunday that he expects new sanctions on Iran weekly, particularly targeting banks, and that Washington intends to cut Tehran-linked institutions out of the dollar system entirely.
âIt may be that the financial pressure was not curtailing Iranian behavior to the level the U.S. anticipated,â Ralby said. Renewed Iranian military activity may also have threatened U.S. forces or interests in the region âat a sufficiently high level of gravity that the U.S. felt it necessary to strike Iranian territory once more.â
The U.S. strike is likely an attempt to break a deadlock rather than a shift in policy, Ralby added. âThe status quo has become somewhat stagnant, and Iâm sure the U.S. would like to see that change,â he said. But it is unlikely to alter âthe continuation of the blockade, or the economic âwarfareâ being used to try to pressure Iran.â
Potential escalation
Trumpâs threat against Kharg Island is likely to remain rhetorical. The terminal has absorbed dozens of strikes since the war began, with its oil infrastructure deliberately spared.
âIt is unlikely that the President of the United States will actually carry through on the threat to attack Kharg Island,â Ralby said, noting the island also holds a historic early church that Iran has worked to preserve.
An attack âwould be a destruction of cultural heritage as well as destruction of critical oil infrastructure, which would likely cause catastrophic environmental harm,â he said. âThreatening it may seem appealing, but actually blowing it up should hold little appeal.â
Rather than confronting U.S. forces head-on, Iran is more likely to retaliate through proxies and pressure on shipping and energy flows.
âThe key to this conflict from the outset has been asymmetry,â Ralby said. âThe Iranians have demonstrated an ability to use limited actual force to inflict substantial, actual harm.â
For instance, the Houthis, who control a large part of Yemen and have held sway over the approaches to the Bab el-Mandeb for the better part of a decade, entered the war weeks ago in support of Iran.
With the Houthis restricting navigation through the Bab el-Mandeb, the U.S. and its allies in the region could face a situation where the two major maritime chokepoints used to export the majority of the Gulfâs petroleum products are âsubject to manipulation by Iran and its partners,â said Michael Ratney, senior adviser at the Center for Strategic & International Studies.
âWe always assume that the Houthis and Iran are part of the same kind of group, but theyâre not,â said Claudio Galimberti, chief economist at Rystad Energy. âThey have worked in the past quite independently.â
Somali piracy, dormant since 2013, has also returned as coalition navies concentrate on the Red Sea and Hormuz. At least five vessels are currently held, including a tanker seized off Al Mukalla on Aug. 20.
âEnhanced pressure on oil production, the energy market, and global shipping are likely to be the focal points for Iranian retaliation,â Ralby said.
The military campaign remains the dominant force in oil prices. Flows through the strait reached roughly 7 million barrels a day last week via the Omani corridor under U.S. Navy escort, according to Galimbertiâs estimates, calling it âa very costly mechanism … but itâs working.â
The strike on Larak threatens to reverse that recovery, injecting fresh uncertainty into commercial shipping through the waterway. âThe expectation is that the flows in the next couple of days probably will be lower, and therefore you should expect the price increase for sure,â Galimberti said.

CNBC Daily Open: Trump wants to floor it on economic growth as Warsh eyes the brakes
The Trump administration saw two embattled officials fending off criticism yesterday as the war in the Middle East flared up again.

Hello, this is Hui Jie writing to you from Singapore. Welcome to another edition of CNBCâs Daily Open.
The Trump administration saw two embattled officials fending off criticism yesterday as the war in the Middle East flared up again, with U.S. President Donald Trump trying to lower pump prices and talk up growth.
Treasury Secretary Scott Bessent also defended the decision to increase bond purchases earlier last month, after investor Stanley Druckenmiller criticized the move.
If you were working late in Asia last night, you may not have caught any of this, simply because Microsoft Outlook and ChatGPT Work experienced outages. I know of more than a few office workers that were secretly grateful for that.
What you need to know today
U.S. President Donald Trump has unveiled a cunning plan to combat high pump prices for Americans, involving his claimed control over 65 billion barrels of oil reserves in Venezuela.
He will meet with U.S. refiners and fuel distributors, looking for ways to expand domestic refining capacity and bring down gasoline prices, according to a White House official.
Prices at U.S. pumps were at $4.08 per gallon on average nationwide Monday, according to AAA data, which is nearly 30% higher compared to the same time last year.
However, there is just one snag. Experts told CNBC that his deal with Venezuela will not lower gas prices anytime soon.
Venezuelaâs oil infrastructure is in a state of disrepair, and it will require about $180 billion of investment till 2040 to return the country to peak production, according to Rystad Energy.
The South American nation is currently producing around 1.2 million barrels a day, down from a peak of 3.5 million bpd in the late 1990s.
Trump also has one eye on the Middle East, vowing to hit Iran âhardâ after the Islamic Republic said it launched an attack on two U.S. bases in Jordan.
The strikes âdestroyed the technical and repair infrastructure, as well as the enemy fighter deployment sites,â inflicting âheavy damage,â Iranian military forces reportedly said, while vowing increasingly forceful responses.
Growth and the Fed
Trump also continued his push for the Fed to lower interest rates, arguing that the U.S. could grow at rates of up to 20% (yes, that is not a typo), and adding such rapid growth should not prompt the central bank to raise interest rates.
âSuccess in growth does not cause inflation,â the U.S. president said. However, growth has never reached anywhere close to the levels Trump is saying, except for one Covid pandemic-related surge of 34.9% in 2020, which notably followed a 28% contraction in the previous quarter.
The most recent GDP numbers, however, are a far cry from the 20% annualized growth touted. Real GDP increased at a 1.5% annualized rate in the second quarter of 2026, down from 2.1% in the first quarter, according to the BEAâs latest estimate.
The presidentâs stance would then put him at odds with Fed Chairman Kevin Warsh, who is expected by markets to hike rates at the Fedâs meeting in September.
Odds for a move at the Sept. 15-16 meeting jumped to 66.1% on Monday, nearly double where they were before Warshâs speech at Jackson Hole over the weekend, according to the CME Groupâs FedWatch tool.
Treasury Secretary Scott Bessent, meanwhile, defended the departmentâs decision to double the planned size of buybacks of longer-dated U.S. bonds.
Investor Stanley Druckenmiller, Bessentâs former mentor, argued that the policy amounted to âprice managementâ rather than an attempt to improve market liquidity, and risked undermining the Treasuryâs credibility.
Outlook and ChatGPT outages
But the most important news for office workers Monday stateside would be that they had a rare reprieve from some of their work, as Microsoft Outlook and OpenAIâs ChatGPT Work experienced outages.
Users reported problems with Outlook, while OpenAI said users may experience problems starting or continuing tasks in ChatGPT Work, temporarily disabling two of the modern officeâs favorite methods of assigning more work.
Anyone who failed to send an email, and then failed to ask AI to write an excuse for not sending that email, finally could legitimately say âI couldnât do it, honest!â

And finally…
FTC sues Amazon, accusing the e-commerce giant of misleading advertisers
The Federal Trade Commission on Monday sued Amazon, alleging the e-commerce giant âsecretly and systematically overchargedâ advertisers on its platform by manipulating its pricing and auction systems.
The lawsuit, which was joined by 22 state attorneys general, argues that Amazon may have reaped more than $20 billion from advertisers by using âhidden surchargesâ dating back to a change to its auction rules that took effect in 2019.
However, the company argues that its auction systems have saved advertisers $8 billion between 2021 and 2025, not cost them extra.
