I know that this isn't really the place to post this but IDK where else to do it and i figured u guys might be able to help me because of your knowledge in technology. So i checked my account yesterday and it showed a 90 dollar transaction that wasn't made by me so i called my bank and had them cancel my card. At first I thought that someone hacked my computer and stole the information but after scanning my computer with Avast, Malwarebytes, and super antispyware it showed no viruses. So what I want to know is do you think that my debit card info was taken from my computer and I can't find the virus or was it taken from a card skimmer on a bad ATM? should i reformat my HDD just in case?
