|Well, I guess its a case of finding its file or files and deleting it - something I tend to avoid except as last resort. Of-course it might just be registry entries.|
There are two possible ways to find it:
Put Optimuminstaller in Search. If it finds it then right click it and see if it gives the path to the program/files.
Run SpyBot. You right click click the entry and it should give these options:
Select this product (probably a check mark).
More details > Jump to location.
Save the results to file or copy them to clipboard.
If you find the information then shout back with the details and we can see if there is some way you can get shot of it.
Always pop back and let us know the outcome - thanks
