Introduction to Computer Viruses

A computer virus is a type of malicious software that can replicate itself and spread from one computer to another. A virus can be attached to an email, downloaded from the internet, or come from an infected USB drive. Once a virus infects your computer, it can corrupt your files, steal your personal information, and damage your system.

There are different types of computer viruses, including trojan horses, worms, ransomware, spyware, and adware. Trojan horses are malicious programs that appear harmless but can damage your computer when executed. Worms are self-replicating programs that can spread across networks and infect other computers. Ransomware is a type of malware that can encrypt your files and demand payment for their release. Spyware is a type of malware that can track your online activity and steal your personal information. Adware is a type of malware that can display unwanted advertisements on your computer.

Types of Computer Viruses

As mentioned earlier, there are different types of computer viruses that can infect your computer. Trojan horses, worms, ransomware, spyware, and adware are the most common types of computer viruses.

Trojan horses are malicious programs that disguise themselves as legitimate software. Once executed, trojan horses can damage your computer, steal your information, and give hackers access to your system. Trojan horses are often spread through email attachments, software downloads, and infected websites.

Worms are self-replicating programs that can spread across networks and infect other computers. Worms can create backdoors on infected computers, allowing hackers to access your system and steal your personal information. Worms can also slow down your computer and cause it to crash.

Ransomware is a type of malware that can encrypt your files and demand payment for their release. Ransomware can spread through email attachments, infected websites, and software downloads. Ransomware can be difficult to remove, and paying the ransom does not always guarantee that your files will be released.

Spyware is a type of malware that can track your online activity and steal your personal information. Spyware can be installed on your computer through email attachments, software downloads, and infected websites. Spyware can monitor your keystrokes, capture your passwords, and steal your credit card information.

Adware is a type of malware that can display unwanted advertisements on your computer. Adware can slow down your computer and make it difficult to use. Adware can be installed on your computer through software downloads, infected websites, and email attachments.
