It sounds like your computer has been hacked, I would also venture a guess that all of your stored info has been compromised. You should definitely contact your local authorities. As for the site being secure, it is. When I spend money here, I either use my debit card, sometimes a credit card. I can also use Bitcoin, I have never had a problem.

There is also a company called LifeLock ® that I utilize to protect our vital information. This company always notifies me when there is activity under our social security numbers. Thus far, it has always been my husband or I who acquired a loan or a new credit card. LifeLock will also reimburse you up to $1,000,000. Once again, the site is secure!
