Yes, this is a known problem (it only applies to Windows 9x - tou didn’t write your OS, but I assume it’s one of the 9x series).

A fix will be included in the next update (in fact, to activate the fix, you’ll have to set something in the avast INI file) - I’ll post more details on this as soon as the update is out…

Thanks and sorry for this problem,
Vlk
