A few months back I was asked to join a zoom meeting. It was a hack, they now keep taking over my computer and ordering items on amazon with saved credit cards (which i have removed now) but they keep taking over my computer and it gives me a screen saying it is a windows scan… which it is not. How do I get rid of this… I have Bitdefender now but still seems as if they are still getting key strokes and they just attempted to get into my amazon account, but could not get anything….. I have used GeekSquad and no help ….. HELP
