Categories & Types of Antivirus

In the first place, there are the so-called “Preventive Antivirus”, which fulfill the function, as its name indicates, of anticipating the infection by intercepting and analyzing all data input and output operations. It should be noted that this type of antivirus to perform its task must be installed on the disk and reside in the memory of the PC, which is why they take up many resources that in the end slow down the computer.

Another type of antivirus is called "Identifying Antivirus", whose primary function is to identify threats that may already be active on our computer, and that affect system performance. To achieve its mission, this type of antivirus analyzes all files on the computer in search of byte strings related to malware.

The last type of antivirus is called "Decontaminating Antivirus" , whose purpose is to eliminate an infection when it has already occurred and attacked the computer. Many of these antiviruses will also try to revert to the state before the infection occurred.
