|OK, I just tried it to see what would happen. There's no icon on my desktop & nothing in Start > All Programs. I did a search using "Windows System Scanner" as my search term & it came up empty.|
I opened CCleaner, Clicked "Tools" > Uninstall tab & it's listed as "Windows System Scanner" with a Java icon. I highlighted it, clicked the "Run Uninstaller" button, now it's gone from the list (it took a minute). I went back to the System Spec page & clicked "Re-Scan Now!" & it's prompting me to reinstall again so apparently it uninstalled properly for me.
I don't know what you did to get a desktop icon? Did you click SAVE instead of RUN?
