Many times, the Windows Control Panel, Uninstall Programs applet proves insufficient for un-installing AntiVirus or Security Suite installations, as a result of which they leave unwanted remnants on your PC. This often then causes problems esp when you go on to install another security program. It’s thus always advisable to use the AntiVirus Removal Tools or AntiVirus Uninstallers for completely removing anti-virus software.
