what is computer virus

Computer viruses affect millions of people’s computers every year. Getting a computer virus has happened to many users in some way or another. On March 26, 1999, millions of people around the world became a victim of computer virus when they opened an email they thought was from a friend or colleague. The email was with the subject line ‘important message.’ The email suggested there was a private document for the user, so it sounded serious. Millions of people clicked on the document and found a smiley face at the end of the message. The email was simply a virus called Melissa. The virus reached into user’s computer and stole 50 email addresses to send the same message to others. This is what a computer virus does to infect your computer.

Are you looking for an easy definition of a computer virus? Here it goes. 

A computer virus is a malicious software program that infects your computer. The virus gets loaded onto a user’s computer without the knowledge of a user and performs malicious actions to damage the system, programs or files. A computer virus runs against your wishes and alters the way your computer operates or stop it from working.

Trojans, Spyware, Ransomware, Adware- What are they? They all are computer viruses. 

All operating systems can catch a computer virus or malware. Even though you’re careful, your computer can pick up viruses through normal Web activities. Most cases of computer viruses come from receiving music, files, or photos from other users, visiting an infected website, viewing an infected website ad, opening spam email or an email attachment, downloading free games, media players, toolbars and other system utilities and installing mainstream software applications without carefully reading the license agreement. Whether you use Android, iOS, macOS, Microsoft Windows, or a Linux variant, your computer can be at risk.

You must be aware of what does a computer virus do? 

Some computer viruses are designed to harm your computer by damaging programs, deleting files, or reformatting the hard drive. Others simply replicate themselves, making your computer run much more slowly and with more difficulty. 

Even less harmful computer viruses can remarkably disrupt your system’s performance, sapping computer memory and causing unexplained data loss and frequent computer crashes.

You must be thinking, why do people make viruses? And what do they do?

Computer viruses don’t just “happen”; they are created often with great care, intentionally targeting computers, systems and networks. But for what purpose these viruses are used?

They are used to infect unprotected systems, gain admin control and hack into your drive and steal sensitive data or just make everything run much more slowly and with more difficulty. Hackers design computer viruses with malicious intent and prey on online users by misleading them. 

Unprotected systems are always vulnerable to computer viruses. An unprotected computer is like an open entrance for computer viruses.

Types of computer viruses?

Types of computer viruses

Macro Virus

A macro virus is a computer virus written in the macro language that is used for software applications, such as word processing programs. For example, Microsoft Word and Excel are widely used programs that feature powerful macro languages. The languages are embedded in documents that run automatically when the documents are open. 

Macro virus can spread through phishing emails containing attachments that have been infected with the virus. The virus will then access the files in the user’s contact list and send an infected email to everyone on the contact list. Macro virus spreads to other computers through software programs that use macros.

A classic example of a macro virus is the Melissa Virus from 1999. Opening an infected email caused the email to send itself to the first 50 addresses in the user’s contact list. 

Boot Sector Virus

A boot sector virus is a computer virus that infects storage devices of computer- hard drive or diskette drive allowing the virus to trigger as the drive or diskette boots. The virus changes the default program with its own corrupted version and can take control of basic computer operations. 

The boot sector virus is created to cause a variety of boot or data retrieval problems. Once a computer is infected with a boot-sector virus, it infects the non-infected disks used by the system. Examples of boot sector viruses are Michelangelo, Brain and Stoned.

Removing a boot sector virus can be tough because it may encrypt the boot sector. In many cases, users may not even know their computer has been infected with a virus until they run computer virus protection software. As a result, users must rely on updated virus protection software that has an extensive registry of boot viruses and the data needed to remove them safely.

Program Virus

Program virus is a type of virus designed to infect other programs. They can modify or destroy files causing system crashes and program malfunctions. A program virus can infect executable program files with extensions like .BIN, .COM, .EXE, .OVL, .DRV and.SYS. These programs are loaded in memory during execution. The virus becomes active in memory and makes copies of itself to infect files on disk. 

Email Virus

An email virus has malicious code that is sent with or attached to email messages. The virus gets activated when a user clicks on a link in an email message, opens it or interacts with the infected email message.

Email viruses can come in different form and different ways. Some of them can be spotted as malicious based on their subject lines which don’t make any sense, coming from a suspicious sender or several other header fields and body content. 

Recipients can find it challenging to identify specific email messages containing malware since these messages appear to be from a trusted sender. This is true in the case of phishing emails that seem to be from a legitimate company asking you to provide sensitive information. 

An email virus may look simple, but one should not underestimate its capacity to damage your computer. An email virus can remove files, cause computer crashes and destroy data. It becomes necessary to remove email viruses, considering the possibility that a cybercriminal is behind it. The longer viruses are allowed to stay on your computer, the more damage they can do. Users must find a computer virus protection program to protect their computer.
