There are many computer viruses and malware out there in the cyber world. The number of viruses is increasing day by day and it is difficult to say exactly how many viruses are there. Some antivirus companies claim to detect around 100,000 new viruses every day.
Viruses can be divided into different categories such as system files virus, boot sector virus, macro virus, script virus, file infector virus, and Trojan horse. Different viruses have different capabilities and can infect different parts of the computer. For example, a system file virus can infect the system files on the computer and make the computer unable to start. A boot sector virus can infect the boot sector of the hard disk and make the computer unable to start.
Most of the viruses are written by hackers and cyber criminals to exploit the vulnerabilities of the computer or to steal the confidential data. However, there are some viruses that are written by researchers for testing or educational purposes.
The best way to protect the computer from viruses is to install an antivirus software and keep it updated.

How many types of viruses are there in computers?
There are many different types of viruses that can infect a computer. The most common type is a file infector virus, which inserts itself into executable files and spreads when those files are shared or copied. Other common types of viruses include macro viruses, which infect documents and spread through email, and boot sector viruses, which infect the master boot record and spread when a computer is booted from an infected floppy disk or CD. There are also a number of less common types of viruses, including script viruses, which are written in a scripting language such as VBS or JavaScript, and Trojan viruses, which are disguised as legitimate programs but actually contain malicious code.
How many computer viruses are found each day?
The number of computer viruses found each day is constantly changing. However, on average, around 5,000 new viruses are found each day. This number can fluctuate greatly, depending on the time of year and the current state of the virus landscape.
The number of viruses found each day has been steadily increasing in recent years. This is due, in part, to the increasing popularity of ransomware. Ransomware is a type of virus that locks users out of their devices or encrypts their files until a ransom is paid. As ransomware becomes more popular, the number of new viruses found each day is likely to continue to rise.
The best way to protect yourself from computer viruses is to keep your software up-to-date. Make sure you install all security patches and software updates as soon as they become available. You should also install a good antivirus program and keep it up-to-date.
If your device does become infected with a virus, there are a few things you can do to try and remove it. You can try scanning your device with an antivirus program, or you can use a program designed to remove specific viruses. If you are unable to remove the virus yourself, you can take your device to a computer technician for help.

Computer viruses are a type of malware that can infect your computer and cause all sorts of problems, from destroying your files to making your computer unusable. They can be spread through email, websites, or even USB drives.
The best way to protect yourself from computer viruses is to keep your computer up to date with the latest security patches, use anti-virus software, and be careful about where you download files from and what you open attachments from.
