Rootkit Runtime3 Mutant/A

[Guest]

Can anyone tell me what the rootkit runtime3 mutant and mutanta variants do please, as I've just found out I'm infected with these. I did notice that when I went to login using passport, the username that was saved is one that has never been used by anyone I know, also the symptoms were that iexplore was open multiple times, hidden, and the window titles were all "Windows Live", so I've probably been used as a spam sender at the very least.

Thanks in advance (I won't say that I'm a technician and consultant cos that makes me feel really stupid. but I do - as a sidenote, the last infection I had on my personal pc was CIH)
