Several protection devices
Whether in an ad hoc or discreet way, an antivirus uses several ways to protect you. One of the most familiar ways is the complete scanning of the computer. Whether initiated by the user or performed on a regular basis, scanning allows you to analyze all the files one at a time and to check them in order to see if they contain a virus. It’s mostly efficient when a contamination is suspected. You may opt to analyze the entirety or part of your files or even focus exclusively on files that are stored on a floppy disk.
During the scanning, the antivirus searches for traces of a virus with the help of its signatures database. Just like every executable program, viruses are made of codes. Every time a virus is discovered, antivirus publishers record codes called “signatures” and incorporate them in their software database. The signature is comprised of a series of characters that are incomprehensible to the users, and legible by the computer only.
