There have been numerous problems with all third party security software and Windows 8, t65hey just don't always play nice.What others have done to solve this- and what I recommend- is to uninstall the third party software and turn on Windows Defender
and Windows Firewall. Windows Defender is more than adequate to protect your computer in Windows 8. Hope this helps and if you need further assistance post and we will be glad to assist you.
