Virus Chest Restore does nothing, Extract... works fine

Avast Free Antivirus / Premium Security
1

Using Avast 10.4.2233 with definitions 151024-0 (today’s). Quick scans ran on two of my Win7 PCs this morning, possibly with yesterday’s virus defs. An installer file from HP (been there long time) was noted to be infected. I let avast move the file into the virus chest on one PC while I investigated. Later, after the virus defs had been updated, I scanned the file while in the chest and avast said “no virus”. OK, just a false positive fixed in updated defs. Scanning on the other PC also said no virus.

The problem is that trying to Restore the file (right-click on file to get menu of actions) from the Virus Chest does nothing. No error. No file restored. However, Extracting the file worked fine.

When Restore fails but Extract works, does that signify anything special other than a possible bug in avast?

Restore puts the file back to the original folder. (Provided the file is no longer considered infected) It leaves a copy in the virus chest.

I know how to use the Virus Chest. What I’m saying is that even though the Virus Chest claims the file does not have a virus, the Restore function is a No-Op. But Extract works fine.

Is this just an Avast bug or is there some hidden meaning?

Bob3160, gave a valid reason why the file remains in the chest.

But I don’t see anything in your posts to state that you checked the file isn’t back in the original location (just that it failed) ?
I think that was what Bob was suggesting.

The original post said the file was not restored - I determined that by looking in the place it should have been restored to. I also did a search to see if it was restored to some other place. Nope.

A thought: The target folder is C:\Windows\Hewlett-Packard\ and that folder requires me to provide Administrator Permission to move a file into it. Maybe that interferes with avast trying to Restore a file to it? I am the administrator on the PC.

OK, just trying to confirm.

Whilst some areas of windows would require admin privileges - I’m not sure if avast would require that to do it - I guess it would depend on what avast function is responsible for the move.

The avastUI.exe is a local user function, but avastSvc.exe is a System user, so in theory that should have no problem.

Presumably you aren’t running avast on a limited user account (not sure if that could be a factor) ?

I will try to seek some guidance on this.
