If I get a cable interent, can my ex still hack into my computer?

There are many ways a hacker can get into your PC and find out what you are doing, obviously this requires you to have an internet connection but it doesn't really make a difference if the problem lies with your PC.

I.e. if he's sent you a picture, a video, a link, an email etc. etc. any one of those things can have a hidden application inside them that runs, records key-presses, web history, etc. This is the most likely cause, as all the Internet Service Provider does is connect you, nothing else.

You have 3 main options:
1, Search and search for whatever could be allowing him to spy on you, look for applications you never installed (these can be remotely installed, he doesn't even have to be within a thousand miles of your PC to affect it)

2, Format your PC and re-install the operating system, this is complex and you'd probably need to pay a PC specialist to do it, can't imagine it would cost that much but it would still cost something.

3, Go to the police, what he's doing is totally illegal and if a restraining order or the likes are imposed upon him, he could be put in prison for repeat offending. Before going to the police I'd suggest talking to him about it, he should not be spying on you.

Changing your provider is unlikely to make any difference.

Good luck.
