[Closed] Prevent spying

[ttecht]

I suspect my computer is being spied on so i will format my pc and change my modem.Is there any information (like my ip address) or method this person can use to find or spy my computer again?I changed my ip adress already but i found out there is something called mac adress on the modem so i will change my modem.Should i change my internet service provider too in case there are more adresses or data of this kind?
