    Dear @gruka

    If F-Secure plugin hosting service process is shown to be using a lot of CPU and disk, it is an indication that the product is currently scanning files. Either a scheduled scan is ongoing or files are currently being scanned by real-time scanning. 

    To make sure that a scheduled scan is not ongoing, follow these steps:

    1. Open the Windows Task Manager by right-clicking the taskbar and selecting Task Manager
    2. Go to the Details tab
    3. Sort by name and check if fsscan.exe is running

    If fsscan.exe is running, a scheduled scan is ongoing. The CPU and disk usage will be shown in the Processes tab to be used by F-Secure plugin hosting service.

    You can change the scheduled scanning settings to minimize CPU / Disk usage and also decrease the scanning time:

    1. Open F-Secure SAFE / Internet Security on your computer
    2. Go to Settings 
    3. Go to the Scanning settings tab 
    4. Change the following settings:
      • Enable Run scanning with low priority 
      • Enable Scan only file types that commonly contain harmful code
      • Disable Scan inside compressed files
    5. Close the settings window to take the settings into effect

    When the next scan is run, it will use those settings.
