I was on my dell laptop looking for editing software and I downloaded one now my computer is in responsive stuck on the slide down to shut down screen the mouse can move and when u rich I see the mark on the pc indicating that it recognises it but won’t change screen, have I been hacked?
What is the 3rd-party software? The best way is to download free video editing software launched by big brands like BlackMagic, HitFilm Express, Cyberlink, etc. or some free open-source editors. They all have official websites with a security guarantee. <Non-public info removed>
