F-Secure Internet Security: withsecure plugin hosting service - High CPU & memory usage

xmaxix

Hi, I have been having performance issues with my new Lenovo laptop which has quite high-specs for my work (11th gen i7 - 16GB RAM) but since using F-Secure Internet Security I have been having constant performance issues linked mainly to the Windows Service " withsecure plugin hosting service" which consumes an incredibly high amount of CPU and memory pretty much crashing my computer.

There is NO scheduled scan (actually I have disabled it) and I have changed the settings to ensure that F-Secure runs in the less possible occasions but still, this issue is still happening and the only solution that I have is to switch-off my laptop (not even a restart sometimes will help).

I have seen a number of articles online highlighting this same issue, but I couldn't find an answer yet, so any help is more than welcomed!

Specs:

F-Secure Internet Security 18.5 with the latest updates

Windows 10 Home Version 22H2 (latest with all current updates)

Hi @xmaxix

Basically, the reinstallation (Remove using UiTool) of F-Secure Internet Security on your computer should fix the issue. Since you have tried several troubleshooting steps provided in the article you found, I would suggest you remove the existing F-Secure Internet Security using our removal tool. You can refer to the article below on how to reinstall it:
