Remove Trojan Horse downloader.delf.12.an

I need help in removing a trojan horse from a system.

AVG 8 pops up with the following notification when you open anything:

Threat detected!
file name: c:\windows\system32\corpolw.dll
threat name: Trojan horse Downloader.Delf.12.AN

I have attached a copy of the hijack this log

Have you run your anti-virus in Safe Mode?
Safe Mode:

You might also download and run malwarebytes. It's a good utility and it's free.
You can get it from:

Disable System Restore and run your suites in Safe Mode again. If you don't disable System Restore it can reappear.
