Starting with your computer itself:
Erase your browsing history and the Saved Files
By going into your setting click on the browsing history options and erase any traces of where have you been and any files that could have been downloaded.
Have a window ready to switch:
This is very important because you never know who can walk in at any time. Along with this memorize the keystroke (Alt+Tab or Commnad+Tab) to change between what you are looking and what you don't mind people looking.
Use untraced Search engines:
There are websites that do not monitor your internet searches and usage. Sites such as Duck Duck Go guarantee that your information is safer rather than other search engines that use "Smart Engines" to memorize what things you see

Use Private Mode on your Browser:
Although this does not guarantee 100% of coverage the information that you send back and forth through incognito/private mode will not be saved on your browser. This is usually activated on any type of browser such a Chrom, Safari, Opera, etc.
To open a tab as this use (Command+Shif+N or Ctrl+Shift+N) , very fast way of surfing safer on you computer.
Changing your Proxy:
For this type of security is a bit more on the technical side but very effective. Downloading a proxy changer will disguise the address of your computer. That is, that the location of where you are actually surfing is going to change making your direct internet address (IP) a bit safer.
This software is usually available in both Free and Paid versions, each one having its owns Pro's and Con's. Our personal recommendation ; Elite Proxy Switcher due to the functionality and ways of use
Switch your Realm with a VPN service:
Similar as a Proxy Switcher using a VPN will get you the ability of changing where your computer is by getting into a Virtual Private Network. What this means is that when you activate this your computer is going to transport to a safe place (Network) where you can have different privileges on the internet.
Simplest one:
Hola internet is an add on service that incorporates itself to your browser and lets you think that you are surfing in a different part of the world. Excellent for Netflix or if you are in Asia and can't see that special image that you are looking for you can find it this way!
More complicated ones:
On a more complicated note there are program that you can download that will make your computer itself think that is in another part of the world. This will make all of the surfing and transmitting of the programs think its somewhere else in the world. Pro's and Con's, as any freeware the advertisement will be abundant on a freeware but with a paid version you get faster speeds and less advertisement.
Our Recommendation is GhostVPN due to the fact that starts as freeware but you can have a paid version which bring more benefits.
Overall we have to always be safe with the information we send and receive so on a final note try to not give your WIFI passwords to anyone, change passwords and try not to use public WIFI if you want to be unnoticed. Aside from that happy surfing!
