Best free lightweight AV application

post #1 of 24
Thread Starter 
Hey so my new job requires me to devlop on windows systems and I am required to have an active antivirus program. This probably gets asked all the time what would you recommend that is light on memory/cpu and free. Having used linux and being net smart ive never had to worry about AV and have not really kept up to date with the AV industory. So what do you guys use ??

Microsoft Security Essentials works very well and never bogged down any system I had (to include an old HP DV1000 lappy).

Avast. Has never failed me. Unlike AVG. Those also use Malwarebyte's Anti Malware and SuperSpyware for safe measure, all freeware. Some detect what the others don't.

I currently use MSE. I've never had a problem. Years ago I used AVG, Avira, Avast and don't recall problems with those either. I think I like MSE the most though.

I also use Malewarebytes (MSE + Malewarebytes = years of goodness).

I use avast on my personal systems, and AVG on other peoples(friends, family). AVG is more obtrusive and is more "mainstream", if that makes any sense.
MSE didn't feel like it was doing much to PREVENT infection, but it's pretty good at cleaning already infected machines from what I've heard(though i use malwarebytes for that myself...).

I second Microsoft Security Essentials.
I've used both avira and avast for years but MSE is the best. It doesnt hog the system, detects and removes faster, and there are no annoying pop up ads.

Another MSE user here. I used to go AV-less but MSE is so lightweight on resources and only has minimal relevant popups that I use it on every Windows machine I have. I even have it on my N280 atom netbook and it still runs great.
