Available Security Software To Prevent Personal Computer Intrusion And Theft Of My Data

Hello Experts -

I am concerned that some mischievous hack might extract gain access to my home computer, copy all my files, and then access my bank and brokerage accounts in a manner similar to that which affected the privacy of Hillary Clinton's server and the DNC's network.

Is there any good commercially software that can be deployed to prevent such an intrusion?

My computer(s) are located at residential address and are connected to the outside world via Comcast thru a D-Link Ethernet Router.  

Thanks for your input.

Gordon,
The only 100% surefire way to prevent hackers from getting into your computer is to not use a computer. I heard quote from a well-known (in his community) hacker once that has stuck with me. I'm paraphrasing but, basically, he was saying that getting hacked is analogous to getting mugged. If you stick to the well-trafficked areas of the internet and don't stray into dark areas, you drastically reduce the odds you will be a victim. Ultimately, Cybercrime is a buisiness. It takes time and effort for to gain access to a computer, by whatever means, so bad guys want the biggest score per man-hour they can get. Yes, get some software (Microsoft's own Security Essentials for Windows 7 or Windows Defender for Windows 10 are excellent and free) and, yes, secure yourself behind a hardware firewall and do the things John Hurst suggests but don't lose too much sleep worrying about being hacked. Hillary and the DNC have lots of money and are, therefore, much bigger targets than you are. Not that you should make it easy for bad guys by opening phishy emails and clicking every cute puppy gif you see, mind you.

You can get a VPN router that only permits access into your home network via secure VPN. That will stop nearly anyone.

Make certain ALL your computers have disabled administrator accounts.

Make sure the user accounts have strong passwords and log off when not in use.

Oh, and even on forums like this, don't give out details such as your ISP (Comcast), the make of your router (DLink) and the fact you have brokerage and bank account details on your computer! At least, not on the public part of it; if you chat with an expert that helps, give them information privately.
Treat the Internet the way you would a stranger, would you tell them this information? And if a stranger walked up to you and said "come down this alley with me, i've got something to show you", what would you say?
