Ok there are what look like a couple of discrepancies such as babylon toolbar/search. (I may be wrong but it won't hurt to check).
Download adwcleaner and run it, remove what it finds (should only be adware stuff).
As for PCperformer, that program is nothing more than Scareware and needs to be removed. Have a look in your list of installed programs to see if it is listed, and if so use Revo free version towards bottom of page, open it up and highlight PCPerformer and select Uninstall, Always run in Adavanced mode.
It should begin the Uninstall procedure, if the program asks to restart itself during uninstall process select No. Delete all reg entries etc it finds.
Then open up CCleaner and run that to remove any temp files left over.
Please remember anything you download should always when offered be run in CUSTOM mode so you can choose not to install any Crapware.
