I'm investigating a new anti-virus solution for my home PC's that will come closest to meeting my criteria. I prefer a "slim", low impact anti-virus. I prefer anti-virus that, on install, does not worm its way through your system and end up entrenched and difficult to remove completely. I prefer anti-virus that is simple. I prefer anti-virus that has a very very small fingerprint on system performance. I understand that the price to pay for these things is "effectiveness" of the anti-virus at preventing and fighting viruses. In the past, my anti-virus solution has been Microsoft Security Essentials on Windows 7 64-Bit combined with imaging regularly and simply being careful. However, recently, my wife's PC picked up a virus and I had to restore from image so I thought this a good opportunity to revisit my anti-virus solution and see if maybe there might be something better you guys and gals know about that might meet my criteria and be better suited for my uses. Thanks!
