As part of my daily routine, I checked for any notifications in the Windows Action Center (white flag in taskbar) only moments ago to see if there was anything I should be aware of. To my surprise there was a message stating that "The computer needs to be scanned", something I had never seen before. Opening the Action Center revealed that Windows Defender was suddenly turned on (alongside ESET) without any intervention from my side. Malwarebytes was not listed in the active anti virus list.
Opening Malwarebytes in order to check why it was not listed showed that it was no longer running in Premium mode:
My license details seem to have completely vanished:
My license is not even close to being expired yet (I renewed my license February this year). I did not touch or change anything to my system that could potentially explain this issue. The last time I checked Malwarebytes (which I believe was only yesterday), everything was still fine.
OS: Windows 8.1 Pro
Malwarebytes version: 220.127.116.117
Component package version: 1.0.342
Update package version: 1.0.4908
I suppose I could just re-enter my license details, but I figured it would probably be better to find out what may have caused this.
What could be the problem here?
