HTML:FakeWarn-A

I’ve seen plenty of posts for “virus alert” viruses, but I want to make sure to take the right steps to remove. I’m getting the pop-ups telling me “taskeng.exe” is damaged and fake Windows Security Alert pop-ups. It references different “threats” like BankerFox.A, and seems to disable SpyBot. Can someone walk me through the removal process?

System details:
Windows Vista Home Premium (SP2)
Acer Aspire X1200
Athlon 64 Dual Core
64-bit OS

I have Hijack This, SpyBot, Avast installed. Avast identifies it but can’t remove it, SpyBot won’t run because of it. Avast identifies it as HTML:FakeWarn-A. Thanks in advance for any help!

SpyBot is not any good, and i would replace it with malwarebytes or/and superantispyware

Check for malware with this

Malwarebytes Anti-Malware 1.50.1 http://filehippo.com/download_malwarebytes_anti_malware/
always update so you have the latest signatures before you scan
click on the remove selected button to quarantine anything found

post the scan log here

Will do, if I can get the machine started again. Went dead as a doornail for no clear reason. Sigh.
