Scanning files stuck at 12 percent, then goes really slow.

Ive noticed that since a few days ago whenever i do a full system scan it will go to 11/12 percent normally but then it stays there for hours, while it still scans for files it does this very slowly and does not go above this percentage and it becomes basically impossible to finish the scan. Ive also noticed it generally being more slugish when i want to scan a single file for example it will take allot longer to start and to abort it. Why is this the case and what can i do?

    Hi @Ilias

    Thank you for reaching out to F-Secure Community.

    Base on the behavior that you've explained about how F-Secure SAFE behave when performing virus scanning on your computer, it may be caused by your hard disk. But to confirm this, I may need some information about your device. Can you provide me the details of the device that is having issue maybe the brand and the model.

    Looking forward to your update.
