When you have multiple fshoster32.exe running (more than 10), that's not malware. We have built a reliability mechanism in our product so that if one component crashes 2 times, it will separate all components into different processes to limit the damage of the crash. This has triggered in your computer. Quite often it is caused by Windows failing to resume from sleep properly and killing and restarting the services.
Our product keeps working normally in this situation and you're protected.
You can recover from this by simply rebooting your Windows and the number of fshoster32.exe processes should return to normal. (If you know how, you can just restart F-Secure Hoster service to have same effect)
