When you attempt to start a program that has an .exe file extension, the program may not start, and you may receive one of the following error messages:
Windows cannot find FILES32.VXD. This program is needed for opening files of type "Application".
Your desktop may appear to be blank. Also, the problem occurs many times when you restart your computer. Even after an anti-virus program has indicated it has cleaned the virus, the registry entry described in the "Resolution" section of this article is still in the registry.
Path to program is not a valid Windows application
This issue may be caused by the Pretty Park virus. The Pretty Park virus creates the Files32.vxd file, and then copies the Files32.vxd file to the Windows\System folder of your computer. Also, the Pretty Park virus modifies a registry key that causes the Files32.vxd file to run when you attempt to run any program that has an .exe file extension.
