So, I have a 2 year subscription of what was the old AIS. Updated to Premium last year and, since that, I'm facing this problem
The Antivirus "died".. The main engine doesn't work, with Windows advising that no antivirus protection is active.. I'm using Windows Defender now.. This is not the first time, but the other time, wasn't this bad.. Was only the main UI that crashed, not the entire thing..
For record, the virus definitions update is automatic.. The program updates isn't and is a 2 weeks Windows install..
