help needed

just got avast 5 but can not scan any single files i have downloaded could anyone please help me

can you explain better ?

What version of avast 5.0, free or pro ?
Are referring to the old trick of using ashQuick.exe (from avast 4.8 Home) for the download manager to call ?

If so, then this doesn’t work in the free version as it has no command line scanner function and that is what the call to ashQuick.exe is for it to scan the downloaded file.

Actually, Logos and (eventually) I determined Avast free will scan files downloaded through a DM.

I just downloaded eicar with Orbit (Avast real time disabled) and it is detected using ashquick.exe and %file% as parameter in Orbit.

OK, a few weird things, now it is working with my download manager Orbit. Edit: I didn’t use the %file% parameter as it doesn’t seem to be required for ashQuick.

  1. I downloaded via https to avoid the web shield blocking it.
  2. The File System Shield detected it first (I have mine set to Ask) and I just said Block.
  3. Then the ashQuick.exe detection kicked in, but all that does is give you an acknowledgement screen no actions.

So it looks like it works again, but doesn’t indicate that the downloaded file has been scanned, and only displays if a detection is made, but no actions as in the normal avast detections.

Yes, that appears to be the case. I’m not sure if these action switches will work in Avast free, but might be worth a try. For me, notification is enough.
