A top antivirus program is an essential security tool for PC gamers. It guards against malware, ransomware and spyware, viruses, identity theft, phishing and other online threats. It should be light and minimally intrusive. It should also have a little impact on your gaming performance.

Many antivirus programs have extra features specifically designed for gamers, for instance a dedicated game booster, which minimizes background processing and optimizes the performance of your CPU. Some have features that block hackers from accessing your personal information and some allow you to play anonymously with your friends via a VPN service.

Bitdefender is an excellent antivirus designed for gamers. It has one of the best malware detection rates in tests, and cloud scanning that has a minimal impact on performance (even during full system scans). It also comes with powerful tools for tuning up the system such as disk cleaners and duplicate deletion of files.

McAfee is another top security software, comes with an advanced gaming feature which places your games over resource-hungry background applications. It has a Game Boost Engine and a variety of other useful options, including parental controls, scheduling updates and system scanning planning and many more. Machine learning and heuristics are also among the most effective technologies available in the market.

Webroot Secure Anywhere can be installed in less than a minute. It is lightweight and consumes only 5MB of RAM when idle, and less than 15 percent of your CPU while scanning. It has a high malware detection rate and includes an extra feature that completely erases all evidence of your online activity, making deleted files impossible to recover.
