It appears that my desktop PC is infected with some malware/virus which is preventing my malware diagnostic/cleaning tools from running. When I try to run MBAM or Spybot, I get the Windows message "Windows cannot access the specified device, path of file. You may not have the appropriate permission to access the item". When I run Avira, it goes all the way through a full system scan, identifies about 13 infections (including ZLOB etc), then just crashes.
I've tried booting in safe mode then running the tools, but I get the same result.
I've also been getting inconsistent boot-up, the occasional blue/black screen and sometimes the PC won't boot at all unless I power off and on again (sometimes twice!!).
I followed the Preparation Guide, downloaded DDS, but when I tried to run it, it just sat there, cursor blinking but no reports, even after 15 minutes. I also downloaded RootRepeal and tried to run it, but it also crashed immediately.
I would greatly appreciate your expert help with this.
