F-Secure 25.2 Error after updating to the latest version

mericsistvan

Hello!

Yesterday My F-Secure Internet Security was upgraded to the latest 25.2 version. After the update it keeps getting error messages as shown in the attached picture. "An error has been encountered and the device needs to be restarted".

If I restart my PC everything seems to be okay for ~20-25 mins, but after that, the same message appears. Also, app history reports that the fshoster64.exe needed 45 sec to start, when under normal circumstances -and before the update- it required only a few seconds to start.

I've read here that restarting the F-Secure Hoster service solves the problem, but it is a temporary solution too, the error is appearing after the aforementioned time. I've also attached the fsdiag report which was taken after the error message appeared last time

Is there any solution for this problem? Any help would be appreciated!

Edit: PII removed
