I ran into a very similar problem a couple weeks ago on a friend's machine. I have a bunch of antivirus tools and stuff on a flash drive, so I took it to her house to run it all. The damn virus wouldn't let me run ANY of them. Even in safe mode.
This may seem like a silly question to you, but have you tried a system restore? That's what I did to her computer. I just restored it to about two months back, and THEN I was able to run all of my tools. Had her computer running like brand new in a couple of hours. I found, like, 36 trojans, worms, rootkits, etc.
If you haven't done a system restore, try it. Go back a couple of months, then you should be fine.
I'll think of something.
