I have tried to uninstall the Sympatico Security Advisor but I can't. I can't find it in the Control Panel. The Sympatico Security Manager is uninstalled. Can you help me?
Try using some uninstallers like Revo Uninstaller, Advanced Uninstaller PRO or IObit Uninstaller. All of them are easy to use and include a lot of useful features.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
