What Is Virus In Computer
A computer virus is a type of malware that, once inside a computer, can replicate itself and spread to other computers. Viruses can damage data, slow down computer performance, or even render a computer unusable.
There are many different types of computer viruses, but they all have one thing in common: they’re designed to cause harm. Some viruses are designed to steal information, while others are designed to damage or delete data. Some viruses can even spread to other computers, making them difficult to contain.
Most computer viruses are spread through email attachments, downloads, or clicking on links in websites or in emails. However, some viruses can also be spread through infected removable media, such as flash drives or external hard drives.
There are a number of ways to protect your computer from viruses, including installing anti-virus software, updating your software regularly, and being careful about the websites you visit and the emails you open.

What are the types of virus in computer?
There are many different types of computer viruses. Some viruses are designed to cause damage to a computer system, while others are designed to steal information or passwords. Some viruses are even designed to turn a computer into a “bot” that can be used to carry out cyber attacks.
The most common type of computer virus is a “trojan horse” virus. Trojan horse viruses are designed to disguise themselves as harmless files or programs, but when they are run, they infect the computer system and cause damage.
Another common type of virus is a “worm” virus. Worm viruses are designed to spread from one computer to another, without the need for a user to run them. Worm viruses can spread very quickly, and can cause a lot of damage to a computer system.
Another type of virus is a “ransomware” virus. Ransomware viruses are designed to encrypt the files on a computer, and then demand a ransom payment in order to decrypt the files. Ransomware viruses can be very difficult to remove, and can cause a lot of damage to a computer system.
There are also a number of different types of “malware” viruses, which are designed to steal information or passwords, or to turn a computer into a “bot” for carrying out cyber attacks.
Many of these viruses can be prevented by using up-to-date antivirus software, and by keeping your computer’s operating system and software up-to-date. It is also important to be very careful about what files and programs you download and install on your computer.
