I saw another thread on here, but I wanted to ask specifically what anti-virus and anti-malware programs do you use?
I use Avira, Malwarebytes, Spybot S&D, Ad-aware and Comodo firewall. I've found that Avira doesn't eat up tons of resources and scans fairly quickly (considering how much junk I have on my drive).
I saw a thread on slickdeals.net for a free year of bitdefender: http://slickdeals.net/forums/showthread.php?sduid=419604&t=2174034
But Bitdefender got some bad reviews: http://www.pcmag.com/article2/0,2817,2351561,00.asp?tab=Reviews
Avira, however, has a lot of very good reviews: http://download.cnet.com/Avira-AntiVir-Personal-Free-Antivirus/3000-2239_4-10322935.html
I know some people prefer Microsoft Security Essentials (MSE), but I can't find any reason to use it over Avira. I know a lot of people prefer AVG or Avast 5.0. Which anti-virus do you use and why do you prefer it?
