After i log in a ZA window pops up. Telling me that symanic norton is on, Which was a 90 day trial. Is on and do i want to override. So i click yes and then eveything is good. But this happenes every time i reboot. Ive removed all the norton/symantic. Do i need to uninstall Window Defender. PC is running Windows 7/Internet explorer. Or should i uninstall ZA and reinstall ZA?
