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:Â 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.
