Hi! I have EXACTLY the same problem. I was working on a customer's
computer and there was a lot of Spyware and Viruses (she did not have
Anti-Virus nor Anti-Spyware protection).
I removed a LOT of the 99% of the parasites on her computer, but could not
get Microsoft Anti-Spyware to show anything but a BLANK SCREEN. In addition
the computer had the following (unsolvable) problems:
UNSOLVABLE PROBLEMS:
1. Microsoft Anti-Spyware shows BLANK SCREEN
2. Lavasoft Ad-Aware to run (fatal error)
3. NOD32 Anti-virus installer will not run
I have run just about every anti-virus/anti-spyware/anti-trojan software in
an attempt to fix this issue but nothing worked (see list below). I suspect
that the problem that you and I have is rootkit related. A new varient of
one of the following: VX2, "A Better Internet" (aka "Best Offers" or Aurora),
or most likely "Hacker Defender".

Defender"
BTW, I finally ran out of time and had to restore the OS from the factory
discs. Hope you have better luck.
