How to uninstall a malware program that doesn't have an uninstall feature

How do I uninstall a suspected malware program that is sitting in my Programs folder? It doesn’t show up on the Windows Programs and Features screen. I have Avast Internet Security and I’ve run numerous scans, but I don’t know how to remove this program other than by just deleting the application file from the Programs folder. It installed itself yesterday when I downloaded some freeware (tut-tut). Any suggestions received with thanks.

Attach your basic diagnostic logs. (MBAM and FRST)

I haven’t got time to do this sorry. I just downloaded Avast Cleanup Premium and deleted the folder.
