If all you want is to get rid of the folder erasing all traces of Limewire that isn't spyware in the first place, but PestPatrol has screwed up by removing necessary files needed to uninstall properly, then there are ways.

First download unlocker and install it (let's just hope PestPatrol doesn't go after that as well) UNLOCKER 1.8.6 BY CEDRICK 'NITCH' COLLOMB

Install it and then restart your PC. Now try to delete the folder. Unlocker will pop up asking if you need help. Choose to delete the folder. Alsoyou might find another limewire folder under programs and one in appdata. Don't know if PestPatrol has deleted them.

Download and install CCleaner CCleaner - Home

Run ccleaner and scan the registry. Then remove all references to Limewire. Restart and your computer should be "spyware free"
