Antivirus is a software that detects, prevents and acts in the elimination of malicious software programs, such as viruses and worms. They are programs used to protect and prevent computers from viruses, to also give the user more security.
There are several ways for a machine to contract viruses.
They can appear through pen drives, emails, and sites with erotic or
questionable content, downloading infected files and programs and by other
means. These viruses and malicious codes are intended to interfere with the
operation of the computer or other device to record, corrupt, destroy data and
transfer information to other machines.
TYPES
OF ANTIVIRUS
Preventive
Antivirus
These antivirus are characterized by alerting or warning in
advance a possible infection. It is normally installed in the memory of the
computer and monitors the functions and actions of the system.
Antivirus
Identifiers
This class of antivirus identifies malicious programs that
can harm the system. In addition, they look for a succession of specific codes
that are associated with these viruses.
Antivirus
Decontaminators
They have characteristics similar to identifiers. However,
they differ because these antiviruses are specialized in decontaminating
infected systems by removing malicious programs. The main objective of this
type of antivirus is for the system to return to how it was initially.
CHARACTERISTICS
OF ANTIVIRUS
§ Protecting the device: They
are programs used to protect computers by fighting again all odds that are
going to harm the computer. Antivirus can record both the files found within
the system and those that seek to enter or interact with it. It can also
recognize a behavior pattern or behavior typical of a virus.
§ Antivirus is different: An antivirus can be
complemented with other security applications, such as firewalls or
anti-spyware that perform additional functions to prevent the entry of viruses.
§ It should not interfere with the operating
system: There are really powerful antivirus programs, but
unfortunately, they consume all the resources of an operating system. If we
have a powerful and up-to-date PC this may not bother us, but if for example we
are laptop users we need an antivirus that does not interfere with the general
performance of our equipment.
§ Detecting of virus: The
most common method that an antivirus uses to detect the presence of a computer
virus is to compare files against a database with virus records.
§ Simple and easy-to-understand interface: A
good antivirus should be our ally and therefore, it should be easy to use
without diminishing its effectiveness. An antivirus with a thousand hidden
options is of little use that we do not know how to use.
§ Presence of different types of shields: A
good antivirus must offer shields both in our activity through the Internet
browser and also through our email client.
§ Protect against zero-day attacks:
Zero-day attacks are threats made by viruses so new that for many programs they
are still unknown or undetectable. A good antivirus must detect them instantly
or within an hour of their appearance. They can also detect malicious activity
to identify unknown viruses or mimic files and record activities performed by
programs.
So, now you are aware with types of antivirus and characteristics
of antivirus and you know how much it is important for all of us. So you should
be having a good antivirus
install with all the characteristics with updated version which can fight with
viruses and keep your data and computer safe.
