You sounds like a security hole. I hope you don't work for any company that lets you access sensitive information. Anyway, here are some suggestions in no specific order:

• (☞ﾟヮﾟ)☞ Change your email's passwords and personal questions (make sure that somebody that knows you couldn't know the question by knowing you, I.E. if you have any inside jokes with yourself)
  
  (☞ﾟヮﾟ)☞ Reformat your operating system.
  
  (☞ﾟヮﾟ)☞ Install a firewall and leave it on. (Pro-mode: buy a router. If you have a router configure it properly.)
  
  (☞ﾟヮﾟ)☞ Use a program similar to noscript if you are prone to clicking on stupid websites.
  
  (☞ﾟヮﾟ)☞ Keep your antivirus up to date, scan everything, don't trust anyone.
  
  (☞ﾟヮﾟ)☞ Make your passwords something less stupid. Make them something like 10 digits of random characters, print them out and don't store a digital copy, keep them somewhere safe. Change them monthly.
  
  (☞ﾟヮﾟ)☞ Don't access your email or steam account from anywhere but your own systems. You can never be 100% sure of the security of any system but your own.
  
  (☞ﾟヮﾟ)☞Don't store your passwords on your computer. (yes, this means having to type in your password every time you log on to skype/steam/messenger/email)
