An antivirus can combat these threats, whether to protect against malicious software from being downloaded when installing mods or to prevent phishing attacks targeting gaming platforms.

We’ve also tried to find gamer-friendly features, such as the option to silence notifications and pause updates during gaming sessions. We’ll also explain how you can get set up and provide tips for keeping your gaming PC safe and optimized for the best possible performance. If you’re in a hurry, check out our shortlist below, or stick around for the in-depth reviews.

Bitdefender Antivirus Free might not have a dedicated gaming mode, but it is lightweight enough that it won’t slow down your gaming. It operates quietly in the background and doesn’t consume significant resources. With it, you can expect real-time protection, safeguarding you from various threats, be viruses, ransomware, or trojans. Bitdefender Antivirus Free is one of only a few free antivirus programs, including live customer support.

Malwarebytes Free differs from Microsoft Defender Antivirus and other antiviruses because it doesn’t offer real-time protection. Despite this, it’s an excellent free tool for detecting and removing malware such as spyware, adware, and ransomware. The free version only allows for on-demand scans, which makes it a lightweight solution for gamers. It doesn’t run in the background or consume resources while gaming, which can help improve performance.

Another advantage of Malwarebytes Free is that it won’t interrupt your gaming sessions with ads or notifications. This is not something that can be said of all free antivirus programs. By pairing Malwarebytes Free with Microsoft Defender Antivirus and its real-time protection, you can have strong, layered security for your PC without significantly impacting gaming performance. They’re both lightweight and won’t be competing for resources in real-time.

Malwarebytes Free provides apps for Windows, Mac, and Android. The iOS app is limited to blocking ads and spam calls.

EXCELLENT MALWARE DETECTION:Malwarebytes Free excels when it comes to detecting different types of malware. Although it lacks real-time protection, it can be paired with another antivirus such as Microsoft Defender Antivirus. Beginner-friendly app.

You’re also protected by Avast’s web and mail shields and its Ransomware Shield – something that not too many free antivirus providers offer.

How we found the best free antivirus for gamers: Our testing methodology

We’ve already compiled a list of the best free antivirus programs. That doesn’t necessarily make them the best free antiviruses for gamers, though. When looking for the best free antivirus for gamers, we emphasize performance. After all, an antivirus is not good for gaming if it doesn’t allow you to play games.

Our antivirus testing methodology sees us examine every aspect of an antivirus, from its ability to detect and remove malware to its independent testing lab results. Of course, we adjust it accordingly based on specific use cases. Below, we explain what we were looking for in a free antivirus for gaming:

• Ability to detect and remove malware: The ability to detect and remove malware is a critical factor for any antivirus, free or paid. Real-time detection is part of this because it ensures threats are quickly identified and removed before they can damage your system.
• Minimal system impact: We look at the antivirus’s CPU and memory consumption when idle and during scans to get an idea of its impact on your system. Of course, we want to make sure that the antivirus software isn’t slowing down gaming sessions, so we prioritize lightweight, free antivirus software.
• Gaming mode or silent mode: Having a gaming mode or silent mode is very important if you want to enjoy uninterrupted gaming sessions. This should silence notifications such as pop-ups during gameplay. A gaming mode may also pause background tasks such as scheduled scans and updates.
• Ease of use: You probably want straightforward protection without complicated setup so you can get on with gaming. The best free antiviruses for gamers have a simple installation process and a user-friendly interface. We also look for automatic updates and alerts that clearly explain any issues and recommended actions.
• Frequent updates: Regular updates protect you and your gaming rig from the latest threats. We’ve specifically selected antivirus providers that frequently update their virus definitions. The ability to automatically download and install updates is also important for updated protection.
• Additional features: When comparing the best free antivirus programs for gaming, it’s worth evaluating additional features which can add extra value and improve your protection. This may be a firewall, a VPN (albeit likely with limited data), or even customer support. The presence of a particular feature might help you reach a decision.
