I have MSN Instant Messenger and was tricked into accepting and receiving the Choke.exe virus. I've deleted all the files attached to it and everything, but it still remains resident in my registry key. I ran an online virus scan the other day and found loads of infected places. I can't tell if it's spreading and making it worse, or just staying there doing nothing. The online virus scan wouldn't let me deleted the infected areas so I have no idea what to do now to get it out completely. Can someone PLEASE tell me how to remove it permanently, because if it is doing damage, it's been there for about 5 months. Another thing i can't tell is if damage really is being done, it's starting to get annoying. I'm finding programs like MSN IM and Adobe Acrobat freezing. First, the worlds get bulky then the window smears and eventually it crashes (OR,it just freezes itself or my whole system), but closing some programs usually helps. I'm taking a guess that it's my memory, i only have 128MB of it and I usually have Winamp, Audiogalaxy, Internet Explorer, Webshots, Zone Alarm, MSN IM and a couple more running at once.
