I am fairly rubbish with computers. This bug has got on my computer yellow triangle logo with black exclamation mark in the middle. There were two other things in the video active x folder but i was able to delete these. The last two pmsngr and pmmon wont even go through my mcafee shredder. Have absoloutly no idea what to do!!!

!! Its also on my toolbar and keeps saying "Security alert: NetWorm-i.Virus@fp
Darent turn computer off but all these links for different bug software keep popping up, along with some advert for a casino! Please help.
Thanks, Nick.
