In this post "Computer Viruses - Detailed
Information in 2019" I am going to tell you about the type of virus
on computer and how they spread. I will tell you this information on the
basis of my experience and after detailed research.
If you are a technology seeker like me then consider reading this previous post " What is computer virus ?? – Detailed analysis" in which computer viruses explained in detail and then came back here.

Types of virus on computer
Honestly, there are an infinite number of
computer viruses found on this earth to study these computer viruses
researchers categorize them into several categories but the truth is this idea
is also becoming useless, as many viruses are being generated every day and
making it difficult for researchers to categorize them
Here are a stats from google report so, that
you may get a rough idea of how many computer viruses are generated per
day.
In 2017, every day 360,000 new malicious
programs are detected every day said a Google report
Over more than 317 million viruses are created
in the year 2015 and this number is continuously increasing causing huge damage
to the economy.
You might want to know "cyber security stats of 2020 ".
Hopefully, you should understand until now
that categorizing every virus is not possible
But here are the most common virus category
that you must know so, that no one can make fool of you.
Boot-sector virus
A boot sector is a computer virus
that directly infects the User's storage device . It is not mandatory that
to infect these viruses Victim as to boot his device. These viruses copy their
malicious code into hard disk partition and if they once saved in memory then
they can infect different part of your computer.
But, thanks to the present day BIOS system
that help to keep these boot-sector viruses away from our system.
Therefore it is highly recommended to keep updated you BIOS at
least.
Resident Virus
Resident virus are the most harmful
viruses according to me as once entered in your system they can install
themselves and the fact that makes them more harmful is they are very difficult
to find out.
Normally, these viruses divide your computer
into two parts
Fast infectors - Those area to which these
resident virus infects more and cause greater damage.
Slow infectors - These are the areas in which
the resident virus infects slowly and cause less damage.
In some, cases these viruses can attach
themselves to your Anti-virus software and making the situation even
worse.
Non-Resident virus
The non-resident virus is also known as
direct action -virus they do not itself get installed in your system instead
they come with the file of common extension like .exe and.docx
but, they do not hinder your system's
performance and can be easily removed by Anti-virus software.
Polymorphic virus
According to a report, Polymorphic virus is
most difficult to remove by Anti-virus software. The reason being is a tricky
part. So, I will try to tell you in simple words.
Anti-virus only blacklists a variant of
viruses from your computer but polymorphic virus replicates it binary codes and
changes it's variant continuously. So, an Antivirus can even take months to
detect this virus in your computer.
Multipartite virus
The multipartite virus can deliver multi
payload. In simple terms, the multipartite virus can spread the computer in
multiple ways or can infect a PC with multiple software or files.
Its two-pronged techniques make it difficult
to remove this antivirus. Even if you clean you device data then this virus
hides in the boot sector and will replicate itself once you open your
computer.
Macro
Virus
A macro virus is not such a harmful virus they
usually come with files like excel and word attach to your e-mails. Normally, an
average antivirus detects and block them.
How do computer viruses spread??
Well, that's not rocket science to understand
how computer viruses spread ?? You the world is connected by the Internet and
of course the internet is responsible for spreading the virus across the
world
Viruses can be spread through the internet in
any form whether its Emails, attachments, files or even links.
whenever you download a suspicious app maybe
it's a virus in disguise .So be careful with your content on the
internet.
Mostly virus comes into your system via E-mail
and software that you download from untrusted sources.
