WHAT IS ANTIVIRUS AND WHAT IT DOES?
What Are Antivirus?
The antivirus are
programs that were created in the early 80s with the aim of detecting and
removing viruses.
With the passage of time, operating systems and the
internet have evolved, which has caused antivirus to be constantly updated,
becoming advanced programs that not only detect viruses, but also block them,
disinfect files and prevent infections from them. Currently, antiviruses recognize
different types of viruses such as malware, spyware, worms, Trojans, rootkits,
etc.
Viruses are computer programs that aim to alter the
functioning of the computer, without the user noticing. These generally infect
other system files with the intention of modifying them to intentionally
destroy files or data stored on your computer. Although not all are so harmful.
There are some a little more harmless that are characterized only by being
annoying.
