As in there isn't somebody out to hack your computers specifically.
Taking basic security precautions will protect you from 99% of cyber threats. These include:
(PS my target audience is those who are not tech savvy.)
1) Using a good Firewall. Most home wifi routers have hardware firewalls built in. These are the best. But in the absence of that, both Windows and Mac OSX come with software firewalls installed. Be sure your ports are defaulted to the stealth mode.
2) Don't use open WiFi connections. (This means any place that offers FREE WIFI) Or else if you do make sure your internet activity is encrypted using Secure Websites (https) or by using a VPN (virtual private network). Attackers connected to the same wifi network can see everything you are doing otherwise.
3) Make sure you are using a good anti-virus software. You can find good sofware for free if you know where to look. For windows users, windows 8+ has good software built in. Win 7 and below can use Microsoft's windows defender. HOWEVER running anti-virus software cannot protect you from all malware, which brings me to my next point:
4) Don't click on questionable web links or download questionable files. I guarantee if you are going to be hacked this is the most likely way it will be done. Downloading questionable items or viewing questionable pages can install software on your computer gaining access to almost all of your data or turning your computer into a bot ready to perform any malicious task the hacker wants including being used to attack others.
4) Finally but very important, make sure you keep all of your software updated. PARTICULARLY WINDOWS. Most software you run these days have auto-update settings. I recommend you turn all of them on.
