Hi, I have multiple viruses on my computer which I can't delete. I tried to look these up on your site and can't find them. They are: MuMu-C [Wrm], BV:MuMuB [Wrm], Win32:lpcscan [Trj], Win32: Pcghost, [Trj], Win32: lpcscan [Trj]. Tried to repair and couldn't. Please offer any advice that you can as to what my next step should be.
