How an antivirus works

The first question you are probably asking is how an antivirus works. Without going into too technical details, we can say that this type of software analyzes every file or program that is about to enter the system. Basically, an antivirus scans that data and blocks it if it matches the "virus signatures", that is the signature archive in which information about the malware is entered.

Unsuspicious files or programs are authorized to enter a security first place, present in some antivirus: it is the HIPS (Host Based Intrusion Prevention System). A further scan takes place in this space: reliable data is circulated, while unrecognized data can enter the system, but only in "isolated" environments.

At that point, the user will decide to open them or not: if it decides not to, those files will end up in quarantine, which is the same fate as malware.
