What is computer virus?
A computer virus is a self-replicating program that repeats itself to a different program. In different words, a pc virus spreads itself into different executable code or user documents.

Viruses are usually sent to the target computer through email attachments. Computers may be a victim because of users’ unsuspecting practices like visiting an infected web site, clicking on an executable file, opening spyware, adware, etc. Such actions allow the virus to unfold to your system. The same may be caused by infected removable storage devices, like a USB drive or memory stick.
Viruses are programmed to bypass a computer’s security system and firewall. Once a breach happens; different files or folders get affected. Some viruses may modify or delete or affect the key features or functions or resources of an application.
List of Computer virus
Here’s a quick explanation of different types of viruses.
1. File Infector Virus
Often called a file injector, it’s a kind of malware designed to cause permanent damages to executable files or make them technically unstable by infecting them.
2. Multipartite virus
These are viruses which move fast, use file/boot infectors, and attack the both executable files and the boot sector at the same time. By attacking both, these viruses may cause more damages than most other viruses.
3. Macro Virus
A Macro virus spreads to a device through those software programs using macros. Microsoft Excel and Microsoft Word can be very popular examples programmed with the ability to execute macros. Macro viruses which are created for these and similar programs may spread by causing infections to related documents every time the user opens a document.
4. Boot sector virus
These viruses infect the master boot record (MBR) of a storage device. To infect a computer, the virus doesn’t essentially have to boot it. Consequently, non-bootable media or devices may be the reason for boot sector viruses to spread. Copy the infected code to the boot sector of a floppy disk or the partition table of a hard disk.
5. Web scripting virus
Categorized as a kind of security vulnerability through different websites to breach web browser security, these viruses allow the hacker to inject/push client-side scripting into a web page. The abilities of these viruses include the bypass of access controls and the theft of your browser information.
6. Browser hijacker
These viruses modify the settings of a web browser without requiring any permission from the user. The purpose of such modification is to inject unwanted or annoying advertising into the browser. A browser can change the search engine, replace the user’s chosen home page, and show an error page.
7. Resident virus
Hiding itself within your computer memory, these viruses load their replication module into the memory. It means no execution is required to cause the infection, but they can infect just about any file stored in the computer memory. With the activation and loading of the operating system, they load and start their functions.
8. Direct action virus
This virus attaches itself to any program file or (.exe or .com) file during its installation or execution. It’s able to spread to another file very quickly and make it inaccessible. These viruses won’t delete your files completely, and you can easily get rid of them using a standard anti-virus program.
9. Polymorphic virus
Complicated by nature, this virus affects the functions and different types of data. Self-encrypted and unidentifiable by a scanner, a polymorphic virus typically duplicates itself by generating slightly modified and usable copies.
