Ad Aware \ Spybot S&D \ AVG free (well all were free)
I just installed a 30 day demo of Nod32. I might go in that direction for a paid AV.
I might also go pro with Ad Aware. There is no time limit on replies if any one else has any. I would "like to" view video's on my computer (I'll emphasize LIKE TO as it is not a 'need to' basis) but it is not that important to me.
However I would like to know what's going on especially if there is something wrong with my pc and if I have become comprimised somehow...
And the malicious software tools from windows as well as their updates (there is so many of them) But all from Microsoft).
