Thanks to both of you for your advice. I went ahead and backed up stuff after deleting the dllhost32 stuff that I could find. Reinstalled windows and everything was working smoothly. After a while I decided to check and see if dllhost32 was returned, or the dllhst3g was back...and sure enough it was there. my wnsxs folder is littered with literally thousands of folders associated with this worm. Today I have reinstalled windows twice (via partition), and I am beginning to think that my partition(which returns everything to its factory condition) is infected with this as well. I can't access this though, so I can't delete the files porperly. I've also noticed that every file associated with the dllhost32/dllhst3g worm has a 'modified' date of 7/13/2009--around the time I had my last computer. I'm wondering what I should do now? I know how to chang ownership of files and delete them...but even AVG won't shred the files once they are in recycling and nothing else seems to work. Is my only other option to get a new (maybe disc) proper version of windows 7? Please help!
