A cyberattack against my sibling started last year and has caused disastrous problems. When I attempted to offer help, my systems seem to have ongoing problems that I can't seem to solve so that I no longer use my computer for anything but browsing and even then have been redirected at times. The persons attacking my sibling are neighbors who built their own Linux internet server and have compromised our cellphones, computers, landlines, etc. Any help to clean up my computer down to the root and keep all the unknow ip addresses from establishing connections would be very much appreciated. Thank you.
