Wast

Overview

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).

Classification

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!

Manual removal

Please follow the instructions below if you would like to remove Wast manually. Please notice that you must follow the instructions very carefully and delete everything that is mentioned. In most cases the removal will fail if one single item is not deleted. If Wast remains on your system after stepping through the removal instructions, please double-check by stepping through them again.

1. Start the registry editor. This is done by clicking Start then Run. (The Run dialog will appear.) Type regedit and click OK. (The registry editor will open.)
2. Browse to the key:
   'HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run'
3. In the right pane, delete the value called 'Wast' or 'WAST', if they exists.
4. Exit the registry editor.
5. Restart your computer.
6. Start Windows Explorer and delete:
   %WinDir%\Wast.exe
   %WinDir%\sysWast.exe
   Note: %WinDir% is a variable (?). By default, this is C:\Windows (Windows 95/98/Me/XP) or C:\WINNT (Windows NT/2000).
