I really don't think you'd have a problem out of a hacker for 2 years. I find that hard to believe. In my opinion, you're doing it to your self.
I'm thinking you're running some sort of program that's cleaning out your fav list and blowing out your passwords.
But if in fact some one is dinking with you then that says you don't have a firewall. ESET has a hardened firewall as part of its security suite. For the money, it's cheap insurance.
You can set it to alert you about traffic on your system. You see something that is not routine, you can block it.
ZoneAlarm is another good firewall. You have to teach it what is allowed and what is not. Again you can see the traffic going in and out and if it's not routine, block it.
Get up with your ISP and insist on a new IP address. Just powering down the router/modem will not always give you a new IP. Most of the time doing a power cycle will net you the same IP.
Get that firewall in place and see what is coming and going.
