Viruses explained: How they spread and 5 signs you've been infected

A computer virus is a malicious code blocks type that is used to replicate and distribute legitimate applicational code. Like any malware, an attacker uses a virus for damaging or manipulating the device. Its name originates from the way its targets are contaminated. A virus of the machine is not an autonomous program. It is a fragment of code that is used in another program. When the program runs, it runs the virus code, and the effects differ from the catastrophic to the annoying.

What are these viruses do?

The virus spreads by infecting those on the host machine, adding its malicious code wherever possible. The boot sector viruses use a particularly dangerous technique at this stage. They place their code in the bootable area of the computer system drives. It ensures that it’s running even before the operating system loads entirely, making it impossible to run the program as it is opened by a resident virus. In contrast, a non-resident virus can infect executable files even if they’re not running.
