What is the LIGHTEST antivirus software for Windows 7?

post #1 of 15
Thread Starter 
I play CS:GO and right now I run Panda Antivirus. When I game I have to disable the program to keep it from causing some stutters in the game. They aren't anything big, but they knock me out of focus which is a problem. So I need the lightest antivirus possible to minimize this issue.

It doesn't have to be the greatest at protecting my computer since I just game, watch youtube and twitch, and browse forums/reddit so I'm pretty low risk as it is. I just need to have something.

Bitdefender is the lightest I have found. Though I had to remove it as it's firewall kept blocking BLOPS3 from connecting. No problems otherwise.

Microsoft Security Essentials or Avast Free.


I've actually used the Silent/Gaming mode with Avast Free in such games as DOTA 2 and CrossFire by Smile Gate with no problems at all.

Voicing the same opinion here as the others. The lightest antivirus I know about is Avast free.

I personally use Kaspersky Internet Security paid version (free is good only for 30 days) as I feel it's the most thorough and solid antivirus out there. I've had Avast's top paid version and they do come close but I do high risk stuff so I have no choice but to pay.

Honestly, your best bet is to just download Avast free and buy Malwarebytes lifetime. Here's why imo.

In short, they've switched over to subscription but you can find copies for 40 to 50 dollars or so on Amazon (I bought 3 copies about 6 months ago). All you do is download the latest software from their website but use your code from the box. Overall, the key code is transferable for life to any other PC once the old one is done. No subscription.

The combination of Avast free and Malwarebytes lifetime will have you covered solid.

As you can see they are going quick.

Thank you everyone! I went with Avast and no stutters since! Might try out some of the other options as well but Avast only uses 10,000K memory or so. I am not sure if anything is less than that.

If you are on Win 8/8.1/10 then Windows defender is likely the lightest as its built in, however its protection isnt that great. I used to use Avast but found it to have gotten heavier over the years and have since switched to AVG. Have the free version on 2 computers and the File server version on my server and its light, easy to use, catches plenty, etc. Also most antivirus programs now a days have a game mode, which should reduce interference when gaming. Personally dont see the need for it but its there for a reason i guess.

Whatever you do please dont use bitdefender. I used to be a huge advocate of it but it seems over the past year or two they have gone to crap. Do yourself a favor and try Sophos home edition its free and you can make one account that allows up to 10 pcs per account (may be more). https://home.sophos.com/login You can easily manage many features from the web also so its really nice, I use it for all my family. Right now sophos running on my work laptop is using about 223 megs of ram and thats the enterprise verison, home is lighter.

Thanks
Joe
