Build a security stack.
Buy OpenDNS Home VIP. $20/year/user. You get protection here beyond your normal anti-virus, anti-malware protection. You can do filtering as well which you can use to blacklist every URL from China, Russia, etc.

Get a good malware protection like Malwarebytes. Either use the free one to scan, or buy the paid one. $50 per year. I personally just use the free one but you have to remember to scan.
Get a decent anti-virus. I just downloaded the free version of Bit Defender. The paid version is like $30/year and gets consistent good reviews.
Use Lastpass or Dashlane to manage your passwords. This is huge, and its cheap and easy to do.
The stack gives you layers of protection and hopefully protects against someone clicking on that stupid email or JPEG(yes I watched the latest episode of Homeland).
