Windows – fool Windows into thinking a virus scanner is installed

anti-virusmicrosoft-outlookwindows 7

I'm trying to allow programmatic access to Outlook without getting an annoying popup. This is configurable under Tools -> Trust Center, however my outlook warns 

Antivirus Status: Invalid.

Which is true because I don't have any antivirus software, nor do I want any thank you very much Microsoft. My question is is there some sort of really lightweight fake virus scanner which will satisfy the condition of appearing to Windows as a virus scanner without actually doing anything?

I am aware this falls firmly in the camp of "Dangerous, but I know what I'm doing"

Best Answer

ClamAV is very lightweight and very free, though I'm not sure it will satisfy MS's security center requirements. Give it a try though, I have yet to see an AV lighter than Clam, and the price is certainly right.
