Do I Need Antivirus For Gaming PC?

It is not always “necessary” to have an antivirus for your gaming PC. However, it is always better to have one!

It depends on how much time you spend on your PC, what you do on it, and if you have a lot of sensitive files to protect. If your game is going to be on the same server as other players though, or if you have a lot of sensitive information that needs to be kept private and safe, then antivirus is definitely something you should invest in.

The thing with computers today is that they can store personal information. Sometimes malware can get on your gaming computer and do something malicious like storing passwords.

So it’s better to have anti-virus for gaming PCs.

Here are some suggestions for antivirus that will work just fine for your gaming PC:

  • Microsoft Security Essential(MSE) is free and has a minimal use of CPU and RAM.
  • Avast is also free and has a lot of features that are useful for the average user.
  • Malwarebytes, not only will remove adware and spyware but also protects against malware and malicious software like keyloggers that can give people your personal information if you happen to click on links from those sources.
