Infected by rouge program PC Optimization Pro...
I have Norton 360 ver 5.2 ...is there any way I can use Norton to uninstall
Are you actually talking about PC Optimizer Pro, Which is suspect, but does not appear to be a Fake program??
Use Revo Uninstaller Free
If this is one of the "extortionware" programs, the best way to be rid of it is to use Ultimate Process Killer while in safe mode. The extortion programs almost always put a strangely named 3 letter (ahY.exe, tLk.exe, Hmo.exe, I always saw them with 3 letters only) auto run executable in the root of C:\Users\User Name\AppData\Roaming.
have to find out which one, as PC Optimizer Pro is freely downloadable from websites
