I've been using the Windows Security Essentials since Beta and have found: - Light resource footprint - Better than decent job in quarantining suspicious files/activity - Fast scanning - Automated updates that actually keep it up to date

And it doesn't get in the way of what you're doing at the time.

Agreed... this is one of the first AV solutions that my work approved of for their VPN solution.

Don't get me wrong, my first preference is *Nix, but work pays the bills and not open source OS. :) I run Windows to get into work...and WSE has been just fine in what I need

I use Microsoft Security Essentials.

  • Microsoft gets all the reports first and has a response center to respond to virus reports, which runs 24/7.
  • Free
  • Updates come down through an internal system; platform updates through Windows Update
  • Only works on "Genuine" installations

I used that once. Completely trashed my Vista x64 machine. Microsoft told me to completely disable everything during the install.. Then claimed they weren't responsible for the virus that killed it.

Replying to your own question... well its a good question and response so you get my vote!

The best question to ask is one you know the answer to :)

Wait, no, that's in the Intelligence biz, not the tech biz... but whatever.

Avast, and Malware Bytes Anti-Malware is another great program, it often removes infections which others don't.

All the way! http://free.avg.com

avg has a bad history of stopping other programs from updating.. steam for example.

I use Microsoft Security Essentials. It is made by Microsoft specifically for their OS and it is very effective. Best of all, its free so you don't need to buy the full version to get all the features.

Funny no one has mentioned COMODO antivirus.. or security suite really. Best firewall and security I've come across, beats every other answer I've seen here. Sure the Microsoft antivirus is light and ok, but there are a lot of things that other security companies do better.. (windows firewall is useless)

For one you can set the security level with Comodo. so you can be paranoid and get every process and file change to ask you first, or you can relax and let it do its thing with out asking you anything

I use Comodo myself. Works wonders. I don't use the AV side, just the firewall. The control is 2nd to none from my experience.

I have been using Kaspersky and Eset NOD32 by far the best paid for solutions, As far as free solutions go AVG Free Edition is ok as well as Microsoft Security Essentials. There is Also an open source alternative called clamwin.

For independant tests of all the different AV software go to http://www.av-comparatives.org/comparativesreviews/main-tests
