yesterday I purchased something online using a credit card.The credit card doesnt belong to me,it belongs to a relative of mine who allowed me to use it.However I'm really concerned that the number doesnt get hacked.The website I purchased from is using a SSL.And I've deleted the info from registry where I think the credit card number was stored (somewhere in Protected Storage).I scanned my computer for viruses at Housecall some days back and no viruses were found.I'm going to scan it again soon.Anything else I can do to ensure that the info is not hacked?
