What is a Computer Virus?

As we have talked about earlier the virus is nothing but a piece of programming code that is designed and written by software professionals to harm computers and obtain results for their benefit.

These professionals develop such harmful programs to attacks other computers when they come in contact with their code and later steal their sensitive information like credit card details, bank details, and personal information for misuse.

These pieces of code are smartly written and can infect other important files present in the computer which can damage the data or even sometimes can delete these files permanently from the computer system.

These viruses which are developed by professionals can reside and hide in the boot record of the hard disk unknowingly to the user.

The boot record of the hard disk is responsible to store important system files which are known for the boot process of the computer.

The viruses can harm or corrupt the system file and can damage the startup process of the computer system these types of viruses are called “BOOT SECTOR VIRUS”.

Computer viruses are capable of contaminating and infecting other computers by duplicating and reproducing themselves as natural biological viruses.

They possess capabilities to copy themselves numerous times and reside in the memory until the memory goes down until the computer system stop responding.

These computer viruses are so deadly that they can even delete the data and format the hard disk drive unknowingly to the users.

Phishing attacks are also performed by hackers when the victim is sent a mail which contains a malicious code

The hackers sent malicious code to the victim via email when users click on the link inside the email they tend to trick users to enter their details which can be used against them.

These files which contain viruses or malicious programs are uploading online by hackers and spammers when downloaded by users can easily infect their system without any knowledge and can damage their system badly.

Different Types of Virus

There are numerous viruses present in the computer world which can be categorized as follows.
  • System Viruses
  • Trojan Viruses
  • Macro Viruses
  • Worms
  • File Viruses
  • Boot Sector or Boot Record Viruses
Different Types of Virus
Different Types of Virus
System Viruses

System viruses are computer programs that dwell inside the boot area and system area of the computer hard disk drive and infect the boot area resulting in damaging the boot process of the operating system.

They mainly attack system files that are command.com, io.sys, and msdos.sys which are very important systems and are primarily responsible for computer booting.

Trojan Viruses

Trojan Horses are a malicious program that is developed and designed to execute destructive codes for breaking down a computer system.

The word Trojan originates from a Greek word that resemblance the Trojan War where soldiers used to hide inside huge wooden horses.

Macro Viruses

Macro Viruses don’t infect program files, for example, EXE or.COM they contaminate application programs, for example, word or speed sheets.

They are the most widely recognized viruses seen nowadays. They are created to harm the application programs.

They normally infect computers when you download certain documents from the web and if the document contains a malicious program your system gets infected.

Worms

These types of viruses harm other computers which are in-network. They are capable of crashing the complete network and spread themselves with incredible speed and hence they hinder the functionality of the computer system to an extent.

File Viruses

The file virus tends to infect executable files like .exe, .com which also are capable of changing the file extension to make them unusable.

Boot Sector or Boot Record Viruses

The boot sector or boot record viruses are also called partition viruses. These viruses are very dangerous and can change the entire partition table of the hard disk drive.

What are the Symptoms of Viruses in Computer

What is Antivirus Software

Antivirus Software is a program or software which scans computers for viruses, malware, and spyware.

These programs are used to detect viruses and help in cleaning, eliminating such files from the computer systems permanently.

Andreas Luning and Kai Figge, who were the founders of the company name G Data Software in 1985, released their first antivirus product.

Antiviruses are designed and developed to scan viruses that are hidden in the computer system.

These help in protecting our system from Adware, Spyware, Ransomware, Key loggers, Backdoors, Trojan horse, etc.

Premium antivirus software is also useful in protecting online transactions, phishing attacks, also used online for safeguarding systems.

The antivirus software contains inbuilt signature and virus definition files. These are robust files that contain the majority of the malware, spyware, and viruses list.

Antivirus software contains virus definition which contains all the necessary information about malware, spyware, and viruses these all information is stored in the database of antivirus programs.
