F-Secure screen switching to not protected.
Switch on PC (Windows 8.1).
F-Secure loads and updates.....all is well. (and updates hourly thereafter)
After a short period of time the F-Secure screen changes to 'Your PC is not protected' (with the red cross)...and says check for updates.
All updates are correct.
The PC was offered an F-Secure upgrade one or two days ago and I accepted....that is the only pertinent activity I can think of.
PC scans are clear.
Before I upgrade 2 other PCs I need to resolve this problem.....Please?
