The best antivirus for PC isn't a requirement for tranquil PC gaming, but if you find yourself wanting of a little extra protection for peace of mind, or if you really are susceptible to dodgy downloads, then one of the packages we recommend below is sure to help.

When you're just about to snatch the winning kill in Valorant, the last thing you need is for Windows to bounce you to the desktop to let you know it has scanned your system and everything is clear. That really annoys us. Like, really, really annoys us. It's not a good antivirus experience. We expect much more from the absolute best, so you'll find little of that from those below.

The malicious software landscape is nothing like it was a few years ago. These days attacks on your system can come from a variety of sources, and while we're still advocates of using common sense and making sure that you don't visit any dodgy sites, that still may not be enough to protect you. At the very least you should ensure the built in Windows virus and protection tool is running.

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. And in the age where more and more purchases are made online, it makes sense to do everything you can to keep your personal information safe. Here are the packages we rate most highly.

While there are many capable antivirus programs 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. 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One of our favorite things about Bitdefender is it can scan for any active vulnerabilities: whether that's out of date software, missing Windows Updates, or even woeful passwords, and it presents this in easy to read reports.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 in case you have a kid who uses your PC. We rarely ever see antivirus programs go the extra mile such as Bitdefender.

Like most antivirus programs, the pricing structure for Bitdefender is based on how many years of coverage you want for five or 10 devices.

Kaspersky Antivirus 2019

As much as we like Bitdefender, there are other capable security suites out there. Kaspersky Internet Security is one of them, and 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.

One reason we like Kaspersky is 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 very good about protecting PCs. Even on the rare occasions, we've run into problems, they've been relatively minor.

You can currently save $30 on Kaspersky and get three PCs covered for a year for $23.99.

McAfee Gamer Security (Image credit: MCAFEE)

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 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.

Webroot SecureAnywhere

When Webroot approached us several years ago about a nimble security product that existed almost entirely in the cloud, we couldn't help but roll our eyes. The level of hype that followed felt like a marketing schtick—here was this new AV program that was supposed to install in under 10 seconds and barely use any RAM or storage, yet provide adequate protection on the level of much bigger security suites. Yeah, right!, we thought. But here's the thing, Webroot was right.

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 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 era of ubiquitous broadband, 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's 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.

Avira Free Antivirus for Windows

5. Avira Free Antivirus for Windows The best free anti-virus It's free! Customizable firewall Reliable protection

Arguing over the best free antivirus is a lot like debating beers. Some prefer a fuller bodied ale with hints of fruits and spices, while others go for a less bitter lager to quench their thirst. And so it goes in our free antivirus category in which we narrowed the choices down to Avira and BitDefender. We ultimately gave the nod to Avira, but it was close.

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 toolchest 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.

Avira's scan engine isn’t the fastest on the block but it routinely racks up awards from independent testing labs, including AV-Test, AV-Comparatives, and Virus Bulletin. You don’t get to over 400 million downloads in the AV space unless you're doing something right, and clearly Avira is.
