Nowadays to many simple virus script created and run from autorun.inf…
In my opinion avast should block application that will run from the autorun.inf except icon for pendrive, software in cd that autorun or authorized program…
Maybe avast can build some application that ask the user to either block or give permission for this type of autorun program…

Go go Avast

Yeah… but avast is not a HIPS program, just an antivirus. Also it is not a behavior monitor. Avast should have better autorun malware detections, this is what they should do imho.
