The folders, were all sub folders of c:\ that wearn't utilised by Windows ie: C:\temp, C:\Photos
I would like to ask you to send the log files so we can investigate where the problem is.
You can simply send them by executing our log collector utility from this path
C:\Program Files\AVAST Software\Cleanup\tulogcollector.exe and once the logs are collected they will be automatically sent to our server.
Once it is done, please let me know which email address you have used there so we can join the logs with your report here.
Thank you.
