I installed this softwear and although it is doing what it supposed to do which is scan your computer for virus, this softwear crash my system when i tried to uninstall it. i successfully uninstall the program but it somehow attached itself to the system and screw it! my MAC is set for a daily softwear update and after i uninstall this program i cannot update my softwear and giving me the error that i cannot use the softwear update and i need to contact the developer of this program! it also created few issues on my HD and when i tried to fix it using disk utility, it cannot be fix. so i need to re-install my OS X to delete all unnecessary program that was left after i uninstall this softwear. so be caution when you try to install this softwear!
