I have the same issue today. Started my comp up, then it said it needed to reboot comp to update to new version. So did that.
Now it just stops responding whatever i try anything with it, and cant close it either in task manager. Did a force restart, and still the same issue, although it says
"UI failed to load"
This is really embarrising
AV service not responding.
All i did see before this was it says something about a version 2.2
I had this installed and working fine for atleast 4 months now..
Trying to do anything with the program in control panel it just says its not accosiated with any app... So nothing can be done there, not even uninstall or change.
Says im using free antivirus, but i have paid for it...
