CleanMyMac
 

I'm running Snow Leopard OSX 10.6.6 and some how or other I seem to have downloaded "CleanMyMac" inadvertently. Can anyone tell me how to remove this program, in detail, please.

It's easy, just delete the application in the Application list. Remember to fully delete its files and component elements.
Ironically, you can delete any application with Cleanmymac with just a click, but I guess, in this case, you'll have to do it all by yourself :)
