The immune/lymphatic system(s)
The organ responsible for filtering and getting rid of wasted blood is the kidneys. They remove waste products from the blood, such as urea and excess ions, and excrete them in the form of urine.
The kidneys are responsible for cleaning the blood by filtering out waste products and excess fluids, which are then excreted as urine.
In the body it is the pulmonary system.
There is a system of the body called the Excretory System. The organs of this system get rid of a certain waste. The skin gets rid of sweat. The lungs get rid of carbon dioxide and water vapor. The liver gets rid of bile, which, in addition to breaking down fats, is partially made up of the breakdown of red blood cells. The kidneys get rid of toxins from the blood. The large intestine gets rid of undigested food. in this way the Dermal, Respiratory, Lymphatic, Urinary, and Digestive Systems work together to get rid of wastes.

There are many ways one could get rid of viruses. One could download programs such as Norton or any other top brand antivirus and they will remove most of the viruses from one's system.
Formatting your computer's hard drive deletes all files on the drive. While it does get rid of viruses, it also gets rid of every other kind of file, including files you may want to keep (like pictures and documents). For that reason, formatting a computer's hard disk and reinstalling the operating system is generally considered a last resort, when viruses cannot be removed by other means.
There are two: the kidneys and the colon (part of the digestive tract).
