Something very odd is happening to my PC in recent days. every time i try to download any file I get an error 'file contained a virus and was deleted’. AVG is seeing a trojan horse: 'trojan horse backdoor generic 17.err', but cannot correct or fix it. it's the same if i turn off AVG virus guard.
Microsoft sercurity client, I was using is no longer available.
I’ve tried to download ComboFix 126.96.36.199, same error and also DDS same error. That’s in explorer 9. In firefox it appears to download, but then can’t open it.
So I downloaded on another laptop. Zipped it up, and emailed to myself onto the infected PC. But can’t extract it.
Then it gets spooky, al least to me. I set up an a/c on bleeping computer, and wait for the authentication email. Nothing arrives. I go to re-validate, no email… did it again, and still no email. Not in spam or junk mail. So I re-register using my work email. And get the authentication email. This virus seems to know I’m after it.
Please help: what can do to fix this one? I’m not an expert on viruses but work in telecommunications and have had PCs for many years, and was an early adopter of the internet.
