Antivirus slows logon while scanning of ProfileUnity Program Files and directories.


Slow logon, Slow logoff, 7z's are created very slowly on the users file share.


Exclude the following scripts and executables. A full list of these with paths is documented below.

For customers on older versions of ProfileUnity (Before 6.5), this KB might list additional executables which are not existing in your client tools directories. There is no harm adding them to your AV exclusion lists as it will benefit after the client tools get upgraded to newer version of ProfileUnity in the future.


ProfileUnity on network shares:


Note: This is the current deployment path. If unsure, check the ProfileUnity console under Administration (top right)->ProfileUnity Tools->Deployment Path.

  • C:\Users\%username%\Appdata\Local\Temp\proux2
  • C:\Users\%username%\Appdata\Local\Temp\proux3
