I've got rid of Norton and I'm trying out NOD32. Seems to be pretty good but I'm having issues with trojans. Is there more to getting rid of a trojan than simply deleting the file? Why can't NOD32 deal with them? I think I've screwed up my system by deleting a .dll file that NOD32 said was a trojan. (probably answers my last question) Being inexperienced I didn't take note of the filename or where it was located. I just clicked 'delete' and thought everything would be sweet. The nod logfile is limited to 100k and had already wiped out the info I needed. Why isn't it 150k? I did too many nervous scans before realising what was up... Bugger!
