Wast drops its main file, wast.exe, in %WinDir% and inserts a registry key to make it start each time a user logs in on the system. I have not been able to find out the purpose of Wast, but there are indications that it is adware related and the general strategy is to remove it [1] [2] [3].

Note: %WinDir% is a variable (?). By default, this is C:\Windows (Windows 95/98/Me/XP) or C:\WINNT (Windows NT/2000).




Wast.exe, sysWast.exe

If you have any of the files related to Wast on your system, please send them for additional analysis. Generally, I have only analysed a few versions for each software component listed at this web site. With your help I will be able to look at both old and more recent versions of the Wast software. Thank you very much for your time!
