The thing is, you need to have a lot more than adblockers, antiviruses and so on in order to beat the hackers... First of all common sense, which is hard to achieve. Secondly you need to know the way things can go wrong / malware can reach your computer or how phishing is able to mislead you. This knowledge is even harder to achieve... Funny things is, I'm an IT expert as well and Data Security specialist and even I have been hacked by a phishing website, which was a perfect https enabled secure certificate fake Ether Delta copy. So yes even the best most secure guys out there can be hacked in a matter of seconds when they make one tiny mistake.
I can guide you in a good direction by advising you to block http websites, check certificates, block plugins or other web services from running outside their virtual sandbox, disable flash player (for sure), keep your browser up to date... As you can see these ar all things you can change by simply setting up your browser correclty :)
