You may get the following error when trying to uninstall HP Client Security:

Error 1325: Hewlett-Packard is not a valid short file name.

The solution, albeit a very odd one, is to disable all CD/DVD drives on your HP system through Device Manager (Start → Run → devmgmt.msc).

After the uninstallation, you can re-enable the device.
