avast4_\UNP244407110.TMP

[Redback]

Is this a valid Avast file?

I have Webroot Spy Sweeper installed on my XP pc, the firewall has quarantined six files with names containing avast4 followed by numbers and letters, one of the files is:

avast4_\UNP244407110.TMP

Spy Sweeper has labeled them as "Mal/Behav-024" - that is malware.

I wonder if these files really belong to avast or are viruses disguising themselves as avast files in order to get through firewalls, as Spy Sweeper seems to think.

Thanks

Those are files Avast has created, they are unpacked zip files or other archive files.

Has Avast found an infection on your computer?

It is a legit file for the temporary folder avast4_, but it isn't an avast file as such, but as Delta mentioned, avast unpacks archive files into that folder to scan them and when the scan completes, they should have been removed.

So there has been a failure to delete the UNPxxxxx.tmp file/s after a scan, why is the question. There is every possibility that it could be malware unpacked by avast, but again it should have been detected and an alert displayed.
