I had F-Secure safe working fine on my Win 10 machine until about two weeks ago. After two Windows updates, it has decided to defualt to Defender, without asking me, and says that 'F-Secure SAFE cannot be run due to security issues'. I tried turning off Defender, and also re-installing F-Secure SAFE. I am basically blocked from using it as my default anti-virus. Freedome works fine, so I don't know what the issue is.
Anyone else had a problem with recent Windows updates?
Have you tried to open the F-secure safe manually by double clicking the F-secure icon? Is your F-secure Safe product working? if yes, you can try disabling the windows defender service by following the steps from this article and to enabling the F-secure safe product as default anti-virus.
Did you check from about which version of F-Secure SAFE you have? Maybe it's not updating as intended and is getting blocked as a result?
Restart your computer
Login to My F-Secure, download and install it again
When updated, restart your computer once again
F-Secure should now be up and running fine.
It's important to restart the computer after uninstalling. This enable Windows Defender.
And when installed F-Secure, ALSO restart, so Windows Defender is disabled correctly and proberly.
I had also this problem - and the Windows Update even deactivated Windows Defender, which is being used on another computer!!! :-D So, perhaps, it did that also with all other antivirusprograms - AVG, Avast!, and what we now can get....
