Avast 4.8 blocks access to network mapped folders on Windows XP64 SP2

Avast Free Antivirus / Premium Security

I have several network locally mapped folders and every time I try to copy something from any of them, avast hangs my transfer and logs error messages (00000005). I have to disable Avast every time i try to copy something from my network (windows workgroup) :frowning:

error sample 1:

AAVM - scanning warning: x_AavmCheckFileDirectEx [UNI]: \\Microunde\Drivere\drivere HP\HP Business 2800n\hpbi2800\Setup.exe (\\Microunde\Drivere\drivere HP\HP Business 2800n\hpbi2800\Setup.exe) returning [b]error, 00000005[/b].

error sample 2:

AAVM - scanning error: x_AavmCheckFileDirectEx: avfilesScanReal of \\Microunde\Drivere\drivere HP\HP Business 2800n\hpbi2800\Setup.exe failed, [b]00000005[/b].

error sample 3:

AAVM - scanning warning: x_AavmCheckFileDirectEx [UNI]: \\Microunde\Drivere\drivere HP\HP Business 2800n\hpbi2800\Setup\Temp\wsnmp32.dll (\\Microunde\Drivere\drivere HP\HP Business 2800n\hpbi2800\Setup\Temp\wsnmp32.dll) returning [b]error, 00000005[/b].

P.S.
It never happed on Windows XP Pro 32.
The network folders are on an Network Storage Unit (NSU) running linux.

This problem is pretty serious and I wonder why no official replay?

Error 5 means access denied. Are you sure you have rights to access that folders/files?
