Scientists encode

computer virus into

DNA

Computer viruses look like the next phase of computer storage. Fascinating! Researchers have successfully written a computer virus into DNA which is able to infect and control computers when read. In essence, deoxyribonucleic acid, or DNA for short, is a genetic database for storing information. This genetic database forms the masterplan for the building blocks of all living things from a cellular level all the way to organs and tissues. Utilising its fundamental basis of data storage, scientists have been leveraging this mechanism to encode DNA to store other forms of information such as books, audio recordings and images. As research and experimentation on DNA storage begins to grow, so does the potential to store a greater variety of data and programs. One such example is the University of Washington’s recent foray into encoding DNA with a computer virus that is fully active. Writing a virus into DNA Wherein most digital data is stored in a binary coding system of 1s and 0s, DNA stores its data in the form of a quaternary nucleotides: adenine (A), guanine (G), thymine (T) and cytosine (C). Knowing this, all the researchers at the Washington team had to convert the quaternary nucleotides into a ‘binary form’ – and sequence the exact code for the computer virus into the DNA’s code. When those recoded DNA strands were sequenced by a genetic analyser, the computer virus would become active and launch an attack against the computer system. Despite being the first team to successfully arm a DNA sequence with a virus, this success has proven to be a double-edged sword with the success of proving that DNA could be indeed used in the future, as a basis of cyber-attacks.

What Viruses Really Do to Computers

Most computers these days have programs that protect them from viruses. These programs not only provide protection against adware and spyware, but also against different kinds of malware. This, without a doubt, is a good thing! ‘Malware’ is a word that comes from ‘malicious software’. Any spyware or virus which can get inside a computer and cause havoc can be termed as malware. A few years ago, computer viruses were the only type of malware present. Those viruses had the task of annoying computer operators in one way or another.

Not just a nuisance Certain viruses are written as nothing but jokes, in order to entertain the creator himself or herself. However, not all viruses are like that. The actual purpose of a dangerous virus is usually to completely kill a computer for good. Sometimes, the goal may be to completely shut down a whole network of different computers. This, usually, is called to be cyber terrorism of a kind. Spyware are almost like viruses. However, there lies a subtle difference. A virus usually has the job of harming your computer in one way or another. However, a spyware is usually written to steal bank account details, passwords etc. Some spyware can harm the operating system directly as well. Rendering machines useless The reason spyware and viruses make a computer slow is because they utilize the resources of the computer to do as they please. They are, at their core, computer programs. So, like all programs, they run on Windows 7, 10 etc. The difference between a normal program and a virus is that the virus does not have an icon which you can use to run it. Viruses run as they like. You do not really have any way to shut a virus down. A number of viruses can even replicate themselves. That means, a single virus can enter your computer, then replicate 100 times, and then totally put your computer in jeopardy. Annoying and disastrous results Spyware can very well make a computer unusable. Even though spyware does not replicate by itself, it is not uncommon for a PC to get 1000 or more infections. With such an amount of spyware present, the system needs to do everything in its power to store and entertain them. In such a situation, it is unlikely that you will be able to launch a program at all, whether it is your browser or MS Word. The thing is spyware and viruses are very much capable of keeping the operating system of a computer so busy that a user fails to receive any response at all, or at most, a very lazy or slow response. Therefore, it is utmost important that you do everything in your power to keep your system free of these annoying culprits. Relying on a capable virus and spyware protector should be a good idea. Also, make sure you get a good registry cleaner. Even though it is not really malicious, registry corruption can slow down a computer very badly. It emerges from day to day use, making a PC painfully sluggish.
