I was making a purchase from the apple store and signed in and had to go to email for two factor authentication. There was an email there for recent purchase and without thinking I opened the pdf and it was a reciete for $499.00 bit coin purchase thru PayPal which I never made. Would bitdefender have caught any malware if I did something wrong? I'm pulling my hair out worried because I'm always telling my wife never open these emails! And I go and do it.
