To say the least, "otshot" portion can be a pain... Try uninstalling the program, or changing the settings within the program.. If you've been unable to uninstall the program, try using a secondary, free uninstaller such as Revo Uninstaller at the link below. Download the freeware version, run it, then remove ONLY the otshot portions that are found.:
Once you've done that, then download the free Hitman Pro program from the link below and run a malware scan using Hitman.. It should be able to find and remove the unwanted programs that might remain.
Hope this helps.
I'm unable to remove otshot. Each time computer starts up there's the otsot skin cannot be loaded, do you want outlook contacts imported. I have never used oulook.
