However, Bitdefender is very reliable and doesn't use a lot of your system's resources, so you won't notice slowdown or drag while it is running. The only reason Bitdefender doesn't take the top spot is that this basic program doesn't have the extra tools that make Avast the better pick. Unless you're in gamer mode, these ads do become bothersome as they pop up and do create a bit of slowdown.īitdefender Antivirus Free: Best basic antivirus software However, Avast will keep monitoring for any malware trying to sneak in and stop it.īecause it is a free program, Avast does have a lot of ads that try and entice you to upgrade to one of its paid programs. This includes popup messages or other notices that tend to interrupt gameplay. When you visit a known gaming site, Avast places it on its gamer list and automatically suspends all non-essential processes, so you have all the resources you need while playing. My favorite feature of all Avast computer protection programs is the automatic gamer mode. That way, they can't be swiped by keyloggers as you sign into online accounts. It also has a password manager that keeps all your usernames and passwords secure. That makes it difficult for adware and internet trackers to target you with ads or sell your browser history.

This includes a VPN that blocks your computer's IP address and location while you're online. It is chock-full of features that even basic paid antivirus software doesn't include.
