A few days ago in the middle of working on Premier Pro software something got stuck
and pixel shapes began to appear in the form of small green and pink figures.
The computer crashed and shut down the software abruptly and windows froze and did not move,
I could not even shut down the computer because the start button did not work. Since it came back a few times,
I returned the computer to a restore point where I bought it and thought it worked out.
But now (after two days) everything is back - the pixels of the characters, the freezes, etc...
Does anyone have any idea what this could be? Is it a virus? Am I being attacked?
Any help will be much appreciated!
