It also would be a good idea to check your computer for viruses. I have been in the computer business over 10 years, and doing it as a hobby for over 20. Once upon a time a computer virus was just to "see what they can do". Not any more. The primary purpose of viruses / spyware is to steal your credit card / debit card / checking / email / etc accounts, or to take over your computer to use it as part of a Distributed Denial of Service. DDOS attacks are what have taken down many large services recently spurred by the wikileaks situation. Anyway, I have seen many many people get compromised & have charges made to their accounts, especially in the last 5-6 years. At the very least, change your email account passwords, scan for viruses & spyware, and keep an eye on all of your accounts. There is no one program that removes everything, but I recommend getting the free version of
malwarebytes and do a scan, let it remove anything it finds. Also run a scan with your antivirus. Be sure to update it first. If you do not have a decent antivirus, a couple of good free ones are
Avast, or Panda's
cloud antivirus. Both have commercial versions available, just be careful to pick the free one unless you need something stronger.
