You may get a Windows message that asks if you want to allow the file WSSetup.exe by Perion Network LTD to install every time you power up or restart your computer. The file is usually loaded from the TEMP folder which means that one of Perion products is already installed on your computer and wants to install additional software or some other applications dropped the installation package on your computer. Since most of the time Perion products come bundled with adware (AdWare.Win32.Gator by Kaspersky) or spyware I recommend you to remove wssetup.exe from your computer.
