Keep your antivirus (and choose a good one) up to date and I also scan with malwarebytes anti-malware, use firefox with keyscrambler, noscript, and ad block. HTTPS isn't going to help one bit if you have a keylogger on your system. If on a wi-fi network within the home take precautions to ensure it is secure, always use password protected networks and keep them hidden.
I have once had my paypal account compromised, thank goodness they only went after the money that was sitting in there and nothing else, but it still took 6 weeks to get that money back. Since then I've gotten pretty paranoid to the point of checking running processes on my system and doing scans quite often.
Also some credit card companies have a service which gives you a temporary card number for online purchases that last only a month or so. There are of course other ways CC info is compromised (even from your pocket) but mainly never let it leave your sight/hand. Maybe carry it in a case that protects it from being read (can't recall the name of the reader thieves use now). Last thing set up notifications via email or phone to alert you of CC purchases that are going on to keep on top of it.
