users have installed the avast-net client on XP Professional SP2.
if they start system scan. it runs fine and they get a result list, all okay.
but if they start the scan again,. they see on the screen, that the last scan is far in the past.
in example in february. but he scans 1 time the week.
what is the reason that the system cant update this date?
the user has only USER-RIGHTS. no admin rights, no-mainuser rights.
the NTFS settings are : GROUP user (he is in this group) has full rights on the folder where avast is installed.
any idea?
