But there are lots of different kinds of viruses and malware, short for 'malicious software', all of which can ruin your day in different ways. We've talked about some of the most damaging computer viruses before. And once your computer is infected, the virus usually does something bad. A virus is any type of code that's designed to spread to lots of different computers whether you like it or not. If a malicious piece of code, a computer virus, gets in, it can take over your computer and make it totally useless, or even turn it into a weapon. But all those different components and connections are also vulnerable. By combining a few different parts, they can use electrical signals to store information, perform billions of calculations per second, and connect you with the rest of the world.
