You need two separate computers for 100% privacy
Make one computer completely private by never hooking it up to the Internet

Building a 100% Private Computer system
In today's world of downloadable content, apps that auto install, online games with ads, and hacking that rarely gets prosecuted, we are finding more computer users want 100% privacy rather than just "better anti-spyware software" which can be headaches to keep reinstalling, paying for and maintaining.
For real privacy, you need two computers; an Online computer and an Offline computer
Make one computer your Online computerUse this computer for the Internet, but don't use this computer for your important work. Use this computer to just do emails, visit webpages and similar mundane tasks. Make your second computer your Offline computerUse an Offline computer to do your real important work that you want to keep private. This can be anything from lawsuit work, making videos, recording music, working on patents, etc. Never hook this computer up to the Internet. Either disable the ethernet port, or put a wad of chewing gum in the port so you can never plug an ethernet cable into it. Disable the WiFi by either switching it off, or physically unplugging the WiFi card. The newer laptops may have the WiFi built in, where there is no WiFi card to unplug. So to make sure there is no WiFi, you are better off not using a laptop as your Offline computer. Instead buy a desktop computer to use as your Offline computer, and make sure you buy one that doesn't have the WiFi built in. Use your Offline computer to do anything you want to keep private (lawsuit work, videos, etc), at least until you want to make it public. Then simply carry the files over to your online computer and upload them onto the Internet, as explained later in this security article.
Never connect these two computers together
(never connect your Online computer to your Offline computer)
Carry any files between them using a little flash drive. For example, you download some photos from the Internet using your Online computer. You then copy them over to a 4gb flash drive. Then you physically unplug the flash drive from your Online computer, move it over to plug it into your Offline computer. Then copy the photos from the flash drive onto your Offline computer.
This gives you 100% privacy
Don't use the same keyboard and same mouse for both your Online and Offline computers. You want to use a different mouse, keyboard and screen for your Online and Offline computer system.
Below is a checklist of equipment needed to set up an Online-Offline computer system. This set up is strongly advised for anyone working on a lawsuit, creating new music, writing movie scripts or other copyrightable materials, working on patents, and similar. Included in this list are backup supplies which are especially needed for someone being harassed over the Internet.
List of Equipment Needed (with approx prices)
#1. $1,400.00 - Two complete computer systems with 4gb or 8gb RAM, with dual core CPUs or higher. Also get two flat screen monitors, two keyboards, etc.
#2. $70.00 - Two printer-scanners (these have come way down in price. Buy two identical ones).
#3. $10.00 - Flash drive (usually 4gb is okay, although for video work 8gb or greater may be best).
#4. $25.00 - Answering machine (either new, or works perfectly).
#5. $30.00 - Office phone (either new, or works perfectly).
#6. $35.00 - Misc. cables, cords, USB cables, etc. Also brightly colored duct tape.
#7. $50.00 - Other computer supplies.Always make sure you save the original Windows install discs should you need to reinstall Windows. If you buy a used computer from someone, make sure you get the Windows discs from that person when you buy it. For example; you yourself may have Windows 7 install discs, but if you buy a second or third comp with Windows XP, you won't be able to reinstall Windows XP unless you have those Windows XP install discs.
Follow this Rule of Thumb for hi tech equipment
Sameness is simplicity
and remember that
Different hardware means more headaches
Try to abide by the rule of likeness or sameness. Buy the exact same type of computer keyboard as the one you already have. If possible, buy 3 of the exact same computers, making one your online comp, one your offline comp, and keeping the third one as a backup. It makes it so, so much easier if you have any problems where you have to reinstall something, or replace a card, etc, etc. Building a Private Computer system as explained on this page is just so much easier when we follow the motto of "sameness is simplicity", and "different hardware means more headaches".
Exception; It's okay to use different types of Flash drives.
Brightly colored duct tape
Now that you have two computers you will be using, you will probably have so many cables it can get confusing. To counter that, you use duct tape to make labels for the cables. Brightly colored duct tape is the best to use. Cut a piece about 4" long, then slowly wrap it onto the end of a cable. Place the tape from 3" to 8" from the end.
Using the duct tape, you can place these 4" pieces on the ends of all your cables. When done, you then use a thin black magic marker to write "what that cable is" on the tape affixed to each cable. For a printer cable you write "Printer". If you have more than one printer, as you should, you write "Printer #1" and "Printer #2" on the other printer cable. Do the same thing with the mouse cables and all other cables and cords you plug into your computers.
For the USB cables, you write "USB" on duct tape on both ends of the cable (3" to 8" from each end). Since you'll be using a flash drive back and forth between the online computer and the offline computer, it is wise to get two long USB cables and have the ends of both meet somewhere close to your desk. On the end of one USB cable you write "USB online" on the bright duct tape. On the other USB cable you write "USB offline".
Vitally needed for someone doing important lawsuit work or investigations, or anything that may be time sensitive where their comp system must always be up and running.
Extra computer that works perfect and is ready to use, but is kept in storage should one of the other computers go down. Extra LCD/LED monitor, a keyboard, mouse, answering machine, office phone, Misc. cables, cords, USB cables, flash drives, etc
Problems are much more quickly resolved when we remember this when purchasing computer equipment. :)
Operational notes; Once you set up both your online comp and the offline comp, remember to never hook up any cables connecting those two computers together. Always keep your two computers completely separate from each other, using only a flash drive to carry files over, and never connect your Offline computer to the Internet (remember to unplug any WiFi cards inside the Offline computer).ZIP filesFor any files you want to bring over from the offline comp, use a flash drive. Absolutely never plug the ethernet cable into your offline computer. It's best to disable the Ethernet card physically, or stick a wad of chewing gum into the ethernet jack on the rear of your offline computer. Remember that a lot of laptop computers have WiFi built in, which may be very hard to disable. To insure 100% privacy and to keep it free from snooping or viruses, you need to physically disconnect the WiFi from your Offline computer. Therefore, it may be wiser to buy a desktop computer that has a WiFi card in it, which you can physically remove, instead of buying a laptop which may have WiFi built in to the motherboard.
If you want to bring over a .ZIP file, it is wise to have a third computer used only to open ZIP files. You can call this computer your UNZIP computer. Once you place a ZIP file on your UNZIP computer, you then open it and scan the files for viruses. When you know they are safe, you can then bring those files over to your offline computer using a flash drive.
Reminder; If you want 100% privacy, be careful about using any laptop, notebook, tablet or any electronic device that uses wireless because many of these now come with WiFi built in, where it's hard to disconnect the wireless aspect of it. Most desktop computers are not like this, so they are safer.
