Challenge: Best/Most Reliable Free Antivirus and Antispyware Software
So as I type, I'm purging my girlfriends computer of the trojans and malware that here system picked up, the kind that after they infect the system, they disable all her hardware including her NIC and install fake antivirus software and block the antivirus she currently has.
First she ran McAfee, till I can along and then she ran AVG, till it went haywire and started sucking massive amounts of system resources for no apparent reason. I switched her to Microsoft Security Essentials and after 2nd time her system has been compromised. I've sourced her problems to our manga/anime websites which often are plaugued by the poisoned ad networks @shrdlu spoke of, however I have never had a problem with those sites, yet.
Anyway, what do the ladies and gentlemen of deals.woot think she should be using?
