Lots of Special Logon events

Good Day, I sure hope someone can help me, I get loads of special logon events n event viewer, and then my wireless internet speed just vanishes, the only conclusion I as a simpleton could come up with is that someone is either spying on me or is stealing my internet and intellectual property. I have attached the saves log below, please HELP.
