Repeated Reports of Malware/Trojan from Windows\Installer

Viruses and worms
1

Hey, I keep getting alerts saying that Avast as blocked Malware/Trojan from somewhere inside my Installer folder. It says that the threat has been contained, but it seems that whatever file is doing this continues to multiply this, and while it seems to be blocked, it is a tad annyoying to put up with. What should I do?
