My computer has been running slow so I checked my computer and found out that I have a hacker who is a joint user with a / next to my username and it took over and this birdnerd62510 has administrative rights. Is there anything I can do cause if I reset my computer to factory settings I dont have the paperwork to get my anti virus back without having to buy it again.Will this fix my hacker problem? If I dont get rid of this jerk soon who knows what they might do.
