Someone is Hacking my Computer and downloading everything I type or Internet Sites I visit?

Can someone please explain. I have firewall and excellent antiVirus protection. My e-mails appear and then disappear. Can anyone redirect or take away my e-mails. I have a website which I designed, someone has overimposed some pictures on the website design. What is happening? My website suddenly died, I used to get lots of e-mail..

Can anyone use my internet connection without my knowledge and use my line using networking and control my computer making it a Zombie. It is possible to find out who it is

If you share your internet conetion yes they can get all you type in your keyboared and screenshots etc.. examples of this is using an unsecured wireless netowork or charing broadband connection
I probably think someone also of your computer. You might have the same connection. Have you ever by even accidentally given a clue to your password. Cause I gave my own friend my password and she kept hacking on to my e-mails. Like when you are soon they might be on your account as well and by this when you are doing something they might be deleting your things. Some has gotten your password and for more info, my suggestion. Go to bestbuy,circuitcity or even target.
