Im pretty sure I won't get infected. I got 2 real time protection FrotiClient which has one of the best Web Filters and MBAM Pro real time as well.
Do you make Routine Images to a Safe Location? I don't see an Imaging Software in your Sig. Do you use Windows 7 for Imaging?
Nope i dont use any imaging software but i do scan my computer once a week. I also format it once every couple months.
Do you do a Quick Format or a Full Format? It is my understanding that, starting with Windows Vista, a Full Format also does a zero-write to all sectors.
