All Windows 10 apps open and immediately close - F-Secure dll injection fshook64.dll listed as cause

Hi,

 

I am getting these errors in the event log when opening apps:

 

Event ID 9, Source: AppModel-Runtime

 

App Microsoft.WindowsStore_11809.1001.8.0_x64__8wekyb3d8bbwe was terminated with error 0xC000047E because of an issue with Windows binary \Device\HarddiskVolume6\Program Files (x86)\F-Secure\SAFE\apps\Ultralight\ulcore\1537179249\fshook64.dll. This could be because the binary is unsigned, contains an untrusted signature, or has been corrupted or tampered with. Refresh your PC to fix this issue.

I have tried uninstalling F-Secure SAFE, then re-opening apps and they work correctly. Reinstalling F-Secure SAFE causes them to not work.

 

Is this a known issue?

 

thanks

 

Anthony
