Thanks. I am totally computer illiterate. I have no idea what you basically just said. So basically I am kind of screwed? I do not surf porn but maybe my husband does (hmmmm....) I know that the version of Limewire was legit but I do know that a couple of times when I tried to download a song and preview it, it stated that there was an error on the file and asked if I wanted to download anyway. I said no but could it have been too late? I believe that I do have a firewall on my windows and McAfee and before I had McAfee I had Norton. I don't know!!! What firewall is the best?
