Hi!

For about the fourth time now I've just had to try and reclaim my PC from a notorious and quite well-known serious infection - possibly rootkit-related - that stops nearly all Anti-Virus/Anti-Spyware applications from running, and also renders my machine impossible to boot in Safe Mode - I get a quick flash of blue if I attempt it and the machine reboots again! However Malwarebytes Anti-Malware (free edn) still seems to run but it finds nothing.

Can anyone offer me a little more info on this, in particular:-

1) How the trojan/rootkit actually stops the security software working;

2) Are there any threads where this problem has already been discussed in detail - I've searched this forum but a lot of the posts are understandably vague!

3) Is there a known threat or is it a combination of several that causes this?

The only way I am able to cure this is a complete repair reinstall which takes up a weekend, & I'm wondering if anyone is aware of a shorter Manual Removal Procedure I can try?

Many thanks,

Chris Williams
