There are plenty of stuff you can do to keep hackers out of your account, one is get a security token. (Wish my WoW one worked with FFXIV) If you have smart phone or another phone or device, you can get it free, or cough up a few dollars and get one. Other mesurements are, change your password every month, you don't have to, but it makes them harder to hack. Second use a more secure browser like Chrome or Firefox. DON'T use IE, worse security ever! download addons like No Script (FF)/Not Script(Chrome) and Ad block plus. this minimizes the chance to get keyloggers, and virus. Also get a good free Virus program like AVG or Avira, in fact I've known Avira picks up viruses better than programs you can by like McAfee's. Also update your windows every patch tuesday and keep your windows defender up to date as well. Even this won't give you 100% protection, but 99% of the time I never got a virus.
