Best antivirus for PC gaming 2021
The best antivirus software is necessary for activities surrounding your PC gaming hobby. In extreme cases, it can actually be detrimental to your gaming experience. But in a world where cyber attacks are worryingly commonplace some protection and all-round peace of mind is worth it.
The last thing you need is for Windows to rip you away from a winning kill in Valorant, just to let you know it has scanned your system and everything is clear—it's just not a good antivirus experience. We expect more from the absolute best antivirus; it should at least be non-intrusive.
But as we sit here and complain, the malicious software landscape is evolving by the second. Attacks on your system come in varying forms, and while we're still advocates of using plain old common sense, i.e. making sure you don't visit any dodgy sites or click any suspicious links, that still may not be enough to protect you. At the very least, ensure the built-in Windows virus and protection tool is running. And for crying out loud don't click any flashy, vibrating web ads!
Better yet, the best antivirus programs listed here will keep your system clean and protect your data from any sinister malware, even on some of the more questionable websites out there. Considering how digitized our lives are today, it's smart to add extra layers of protection, to keep your personal information safe.
While there are plenty of capable antivirus apps on the market, the best antivirus for gaming should do its job without hindering your performance or being too intrusive in your day-to-day use. What makes Bitdefender so good is that, once it's installed, it immediately goes into Autopilot mode. Autopilot makes all the security-related decisions for you based on your usage patterns, so you aren't bombarded with alerts and notifications. Don't worry, though; you still have plenty of control if you want it as well.
One of our favorite things about Bitdefender is it can scan for any active vulnerabilities: whether that's out of date software, missing Windows Updates, or even woeful passwords, and it presents this in easy to read reports. It has its own VPN and improved parental controls if you have a kid who uses your PC. We rarely ever see antivirus programs go the extra mile as much as Bitdefender does.
Like most antivirus programs, the pricing structure for Bitdefender is based on how many years of coverage you want for five or 10 devices.
As much as we like Bitdefender, there are other capable security suites out there. Kaspersky Internet Security is one of them. In this instance, we recommended paying the $10 extra for Kaspersky Total Security, a more fleshed out package with some handy utilities instead of just fluff.
Among the additional grab bag of goodies is a file shredder that overwrites deleted files. Hence, they're near impossible to restore, the ability to create encrypted folders to keep sensitive files from prying eyes, password syncing among multiple devices, and PC clean-up tools, to name just a few. You can find free alternatives to all of these, but having them all in one place is convenient.
We like Kaspersky because it consistently performs well, both in terms of identifying and blocking malware and having a minimal impact on system performance. That's not to say it's perfect—we recall one particularly annoying incident where Kaspersky had let a potentially unwanted program (PUP) lock our mouse cursor in a box. It took some persistence (and Safe Mode) to fix the problem. For the most part, however, Kaspersky is excellent about protecting PCs. Even on the rare occasions we've run into problems, they've been relatively minor.
There are currently half price savings for new customers on Kaspersky, too, so you can get three PCs covered for a year for $29.99.

McAfee has always been a big name in the antivirus world. Chances are if you bought a PC in the early 2000s, it came pre-loaded with McAfee antivirus software. Fast-forward to today, and McAfee has made an antivirus specifically for gaming. It streamlines the process so you can rest easy, knowing that you can still play Apex Legends without having your performance bogged down with security-related pop-up notifications.
McAfee Gamer Security knows when you're in a game, and it will stop anything running in the background as you play. It makes gaming a priority for system resources, mutes notifications, and anything else that would interrupt your fun. It's great for someone who wants to know they are protected from all the usual bad actors online but don't want to tinker around with any settings. McAfee Gamer Security does it all for you.
SecureAnywhere was and still is a remarkable outlier in AV. It takes up just a few megabytes of disk space and uses about 5MB of RAM when idle. During an active scan, Task Manager shows SecureAnywhere using around 50MB of RAM and less than 15 percent CPU utilization, yet it takes just a couple of minutes to scan 150GB of data spread across two SSDs.
Webroot also makes a special version of SecureAnywhere for gamers. It differs from the regular version in that it offers a system optimizer tool to "analyze your devices and the operating systems to detect system issues, wipe away all traces of online activity, and make deleted files unrecoverable." In practice, we only saw it delete temporary files to free up some disk space. SecureAnywhere also politely stays in the background, so you're not bothered by updates or added lag when playing games.
Since it's cloud-based, SecureAnywhere works best when there's an Internet connection. In the ubiquitous broadband era, that's not going to be a problem for many people, particularly gamers. And, though it's lightweight and short on local storage requirements, SecureAnywhere is surprisingly high on adjustable settings. There are well over 100 of them, and you can export your settings to make setup on another PC quick and easy. In terms of pricing, Webroot is currently at $19.99 for a single device for one year (ignore the countdown, it's always that price).
We chose Avira because of the level of customization available. Whether you want to duck your head into the software's menus and start fiddling with knobs and dials is up to you, but if you do decide to tweak Avira's behavior, you'll find a modest tool chest of options. One setting we highly recommend enabling is to search for rootkits before scanning. It will increase scan times, but rootkits are particularly nasty in how they dig their hooks deep in the OS, so it's better to err on the side of safety.
You can also configure how aggressively Avira scans for zero-day threats through heuristic analysis, which is set to a medium detection level by default. Cranking it up to high puts Avira in an extra cautious state but at the risk of reporting false positives. Putting it on low has the opposite effect, or you can turn off heuristic analysis altogether, an option we don't advise.
What you don't get with the free version of Avira is a Game Mode. And though Avira doesn't cost any money, you pay for it through the annoying ads. This is where BitDefender's free version has the advantage. In contrast, it doesn't use ads, nor does it nag users with pop-ups, and it pauses system scans when you're gaming. It's a no-fuss solution, though the downside there's not much in the way of options, just a couple of on/off switches.
