The ones that seem to have the viruses worms from what Ive come across are mostly the T3 or the T1s and higher connections thats why I try to stick to fellow cable users for downloads. I try to filter those out and I also avoid modem users as they can have zip files with viruses in em too. those higher up connections out instead of blockign em. im not a geek so I dont want to spend too much time fussing with my settings.
