Ofcourse you can create a screenshot.
There is a PrintScrn button on your keyboard
- Hit it
- Open paint (or any other image editor)
- Select > paste as new image
The entries do seem to be pup's to me.
Try this:
- Disable avast self defense
- Try to empty the keys (do not delete the keys themselfs)
Do not forget to enable the avast self defense again !
