Add the following folders as exceptions to TrendMicroSystems Worry-Free Business Suite:
C:\Windows\SysWOW64\LvMask (incl. all sub folders) or C:\Windows\System32\LvMAsk [32bit Systeme]
Add the installation paths of the LV to the software as an exception.

Error message during installation: “An error occurred while copying the data”.
Issue resolved: The installation program runs automatically with administrative rights. Please check if the selected installation path (or drive) is mapped for the administrator (drive letter assigned) and not only for the user running the installation program.
If necessary, the program is still in use by another user and cannot be overwritten by the installation file.
To resolve this problem, you can configure Windows to make network drive mappings known in all logon sessions of the current user instead of just one. To do this, create the following in the registry in the key

or delete all .TXT files in FEM folder of program directory (C:\Program Files (x86)\LV\Fest\Fem)

After that everything works fine again.
F-Secure reports virus or unwanted program in file LVPipeOPGL2.exe or deletes the file unasked. This means that the graphics in LV PIPE II no longer work.
It’s a false positive in F-Secure’s heuristics. The file is required for the Pipe program.
The file ‘LVPipeOPGL2.exe’ was classified as ‘FALSE POSITIVE’. This means that this file is not dangerous and is an error message from F-Secure.
The detection pattern is removed with the current update of the F-Secure virus definition file.

AVIRA reports virus or unwanted program in file PipeDXF2.exe (‘TR/Dropper.Gen5).
This is a false indication in the heuristics of Avira. The PipeDXF2.exe is required for the program Pipe.
You can define exceptions in Avira so that the message does not appear again. To do this, enter the PipeDXF2.exe at ‘System Scanner >search> exception’ and at ‘Real-time Scanner >search> exception’. The file ‘PipeDXF2.exe’ was classified as ‘FALSE POSITIVE’. This means that this file is not dangerous and an error message from AVIRA.
The detection pattern is removed with the update of the virus definition file (VDF) 18.104.22.168.
