Hello everyone, This is my first time posting on this forum so if I make a mistake i'm sorry. The problem started 2 weeks after I got a used computer from my uncle.My mouse started acting crazy. I can be just browsing the internet and then my mouse starts jumping all over the screen as soon as I touch the touchpad or during it. I've reinstall windows 3 times and used various anti-virus, anti-malware,etc trying to detect if it's a virus but they all come back negative!. For every time I reinstall windows, the mouse doesn't act up for a while and then two days later BAM!! it's jumping around the screen again. I know that this is symptoms of someone hacking me so I am wondering if there is a way to remove the hacker. Here are some other symptoms I encounter. 1. My graphics driver and mouse driver is uninstalled after a restart sometimes. 2. Windows lags up and shuts down. 3.After a mouse attack or weird encounter, my network card completely stop working and the light blinks on and off. I have ALSO noticed that Computrace is installed in bios and I have read that it is vulnerable to hackers and I was wondering if theirs any BIOS mods for me . I have also noticed that after flashing BIOS my computer started acting up. Laptop: Lenovo 3000 N200 THX IN ADVANCE.
