There's a way. HijackThis has an uninstall list and it can remove everything ( as it's all about the registry values, that HijackThis is a great tool ).
You could post the list on this forum , and tell me what is the name of the program you want to delete.
To do so:
- Open HijackThis.
- Click on Open the Misc Tools section.
- Look under System tools.
- Click on the Open Uninstall Manager... button.
- Click on the Save list... button.
- It will prompt you to save. Save this log in a convenient location. By default it's named uninstall_list.txt.
- Notepad will open. Please copy and paste the contents of this log in your next reply.
See in this link details.
