What Is A Computer Virus? Its Different Types?
A computer virus is a fragment of software that spans from one system to another and causes issues with its operation. A computer virus has the potential to corrupt or erase data.
It uses an email application to propagate the virus to other computers, and it can even wipe the hard drive clean. Computer infections are commonly propagated through email attachments or instant messaging conversations.
You should never open an email unless you know who sent it. Computer viruses can also be propagated via Internet downloads.
They can be found in pirated software and other files and programs that you may download.
1. Trojan horse
A trojan horse is malicious code software that disguises inside other programs. It hides behind a legal program, such as a screensaver, to get access to a computer.
The malware then injects code into the operating system, allowing a hacker to access the compromised computer. Trojan horses are not propagated by themselves; they are spread by Worms, viruses, or downloaded software.
Spyware can sneak into your computer and install itself without your knowledge. These apps can alter your computer’s setup and collect advertising files and data.
Spyware can monitor your online search behavior. It may also redirect your browser to a website other than what you intended to visit.
A worm is a computer code that multiplies without the user’s knowledge. Most worms start as email attachments that contaminate a computer when accessed.
The worm searches the infected computer for files containing email addresses, such as contact lists or temporary websites. The malware uses the addresses to send contaminated email messages.
Worms then automatically spread via email, networks, or operating system flaws. Worms aren’t necessarily dangerous to systems, but they frequently cause performance and stability issues with computers and networks.
4. Rogue software
A rogue antivirus program tries to trick you into thinking your machine is afflicted with a virus. It will typically ask you to download or purchase a virus removal program.
Antivirus, Shield, Security, Protection, and Fixer are frequently used in the titles of these products. They typically begin running after you download them or the next time your machine boots up.
Rogue antivirus software can prevent apps from starting, such as Internet Explorer. Rogue security software may mistakenly present vital and lawful Windows files as infections.
The following phrases may appear in error messages or pop-up messages:
- Your PC has been infected with a virus.
- Your PC is Infected!
- Spyware and adware have infected this machine.
