best antivirus for gaming pc

In this day and age, gaming PCs need fantastic performance and protection from online threats. Choosing the best antivirus for gaming PCs is essential to ensure a smooth gaming experience without worrying about third-party intrusions.

These intrusions or threats can come in various shapes, but focusing on the goal of these apps also tells us what we will need protection from. A good antivirus software will protect your device from malicious threats that can ultimately steal personal information, cause damage to your device, and disrupt your gaming.

Good antivirus software will protect your device without straining your PC’s performance too much. Any experienced gamer can confirm how much a gaming session can be affected by just a few FPS (frames per second) fluctuations.

The best antivirus for gaming PCs should be lightweight and efficient so it doesn’t take up valuable system resources or cause lagging during gameplay. It works in the background quietly, detecting and removing any threats without affecting your game.

Some antiviruses include a Gaming Mode that covers these aspects, and some have a performance booster. We’ll cover all these aspects in today’s list.

How We Tested

To create the software list below, we have tested all popular antivirus software available, making sure to close any other applications that could affect the outcome. We chose 5 of them out of more than 16 software options tested. These benchmarks were performed on an ASUS TUF gaming PC with an AMD Ryzen 7 4800H CPU, 8GB RAM, and an Nvidia GeForce GTX 1660 Ti GPU.

Your device needs to be protected from online threats even when you’re playing, and a streamlined gaming experience doesn’t include closing pop-ups from the antivirus software.

For these reasons, we’ve tested the most popular antivirus software, looking at the following features:

  • Malware detection rates – Knowing how effective an antivirus is at identifying and neutralizing threats is one of the most critical aspects of this type of software. We’ve used the AV-Test and AV-Comparatives to explore every antivirus thoroughly.
  • Performance impact – We have checked every antivirus software’s RAM and HDD usage while playing games like Atlas Fallen and Wild Hearts. For comprehensive results, both games were run at different graphics levels, including low, medium, and high settings.
  • Gaming mode or Game Booster – Using an antivirus that suspends notifications and CPU-intensive scanning during gameplay can significantly improve your experience.
  • Additional features – We also explored the other valuable features of these antivirus software, like cloud-based scanning, device cleaning, etc.
