Explorer and Cffmon threat found.

Every Scan after opening windows finds the following

Tracking Cookie - ratbag@atdmt.com/
Worm.Autorun - C:\explorer
Backdoor.trojan - C:\Windows\system32\cffmon.exe

My Automatic updates are turned off and my system restore is off.

avast, even as boot scan cannot find where this is origin of these unsafe files.

The other error that occurs is that on shut down I get 2 cmd.exe errors. After this I have to select shut down a second time to shut down.

ANY HELP OUT THERE?

Hi,
Sorry for taking forever… Having a mare. I have managed to damage my registry following online guides! This has prevent me from installing superantispyware.

I have also to mention that Windows defender fails to work, it will not start. even after a uninstall - re-install. Additionally the prime child culprit’s account is no longer visible on the start up screen. I can log on using Ctl-alt-del though.

I ran the malware, the file log is as follows:
