The different types of computer viruses
There are many different types of computer viruses out there, and new ones seem to crop up every day. Here is a list of some of the most common types of viruses:
1. Trojans: Trojans are one of the most common types of viruses. They are programs that masquerade as legitimate programs but actually contain malicious code that can damage your system or give hackers access to your computer.
2. Spyware: Spyware is a type of malicious software that is installed on your computer without your knowledge. It collects sensitive information about you (such as your browsing habits and credit card information) and sends it back to the hacker who installed it.
3. Adware: Adware is a type of virus that displays annoying pop-up ads on your computer. It is often bundled with free programs that you download from the Internet.
4. Worms: Worms are viruses that spread themselves by replicating themselves and sending copies to other computers on a network. They can cause a lot of damage because they can quickly fill up a hard drive and bog down a network.
5. Ransomware: Ransomware is a type of virus that encrypts your files and demands that you pay a ransom (usually in Bitcoin) to the hacker in order to get the decryption key.
6. Rootkits: Rootkits are a type of virus that gives the hacker full control over your computer. They are very difficult to detect and remove because they are designed to hide themselves.
7. Bootkits: Bootkits are a type of virus that infects the boot code of your computer. This allows the hacker to control your computer even before the operating system loads.
8. Browser Hijackers: Browser hijackers are a type of virus that changes your browser’s homepage and redirects your search queries to malicious websites. They are often installed without your knowledge when you download free programs from the Internet.
9. Keystroke Loggers: Keystroke loggers are a type of virus that records everything you type on your keyboard. This information is then sent back to the hacker who installed it.
10. Fileless Malware: Fileless malware is a type of virus that resides in your computer’s memory and does not create any files on your hard drive. This makes it very difficult to detect and remove..Visit Site
