What are computer viruses?
Computer viruses are small pieces of software that can infect and damage computers. They are often spread through email attachments, downloads, or websites.
Once a virus has infected a computer, it can cause a wide range of problems. It may delete or corrupt data,slow down the computer, or even make it completely unusable.
Viruses can also be used to steal personal information or login credentials. They can even be used to take control of the computer and use it to send spam or launch attacks against other computers.
How can you protect your computer from viruses?
There are a number of ways to protect your computer from viruses. You can install anti-virus software, which will scan your computer for viruses and protect it from infection.
You can also avoid opening email attachments and downloading files from unknown or untrustworthy sources. You should also be careful about clicking on links in emails, as these may lead to websites that contain viruses.
It’s also a good idea to keep your operating system and software up to date, as many of the latest viruses are designed to exploit outdated software.
How do computer viruses spread?
Computer viruses can spread in a number of ways. They often spread through email attachments, downloads, or websites.
They can also be spread through infected USB drives, instant messaging programs, or social media platforms.
What are the symptoms of a computer virus?
The symptoms of a computer virus can vary, depending on the type of virus. However, some of the most common symptoms include:
– Slow computer speeds
– Corrupted or missing files
– System crashes
– Blue screen of death
– Unwanted pop-ups or ads
– Identity theft

What is computer virus explain?
A computer virus is a type of malware that can copy itself and infect a computer. Viruses can cause serious damage to a computer, including deleting files, corrupting data, and even rendering the computer inoperable.
Viruses are typically spread through email, downloading infected files, or visiting infected websites. Once a computer is infected, the virus can spread to other computers on the network.
There are a number of ways to protect your computer from viruses, including using anti-virus software, keeping your software up to date, and being careful about what files you download and where you visit online.
What are computer viruses and its types?
What are computer viruses and their types?
A computer virus is a type of malware that, once it infects your computer, can cause a variety of problems. These can include making your computer crash, making it difficult to use, or even stealing your personal information.
There are many different types of computer viruses, but the most common ones are:
• Trojan horses: These are programs that look like normal programs, but actually contain a virus that can infect your computer.
• Worms: These are programs that can spread themselves from one computer to another, without needing to be installed.
• Spyware: This is a type of virus that can track your activity on the internet and steal your personal information.
• Ransomware: This is a type of virus that locks your computer and demands a ransom payment in order to unlock it.
How can you protect your computer from viruses?
There are a few things you can do to protect your computer from viruses:
• Install antivirus software and keep it up to date.
• Install a firewall and keep it up to date.
• Be careful what you download and open.
• Don’t click on links or download files from unknown sources.
• Be careful what you type into your web browser.
• Use a pop-up blocker.
• Regularly back up your data.
What are the 3 types of viruses?
There are three types of viruses: bacteriophages, DNA viruses, and RNA viruses.
Bacteriophages are viruses that infect bacteria. They are the simplest type of virus, and they are made up of a protein coat and a strand of DNA or RNA.
DNA viruses are made up of a protein coat and a strand of DNA. They can infect both animals and plants. HIV, the virus that causes AIDS, is a DNA virus.
RNA viruses are made up of a protein coat and a strand of RNA. They can only infect animals. Ebola, the virus that causes Ebola fever, is a RNA virus.
What are the 4 types of computer viruses?
There are four types of computer viruses: boot sector viruses, file viruses, macro viruses, and script viruses.
Boot sector viruses are the oldest type of computer virus. They infect the boot sector of a disk, which is the first sector of a disk that is read when the computer starts up. Boot sector viruses can infect the hard drive, floppy disk, or CD-ROM.
File viruses are the most common type of computer virus. They infect executable files, which are files that can be executed or run on the computer. File viruses can infect the hard drive, floppy disk, or CD-ROM.
Macro viruses are viruses that infect documents. They are written in a programming language called Visual Basic for Applications, or VBA. Macro viruses can infect the hard drive, floppy disk, or CD-ROM.
Script viruses are viruses that are written in a scripting language, such as JavaScript or VBScript. Script viruses can infect the hard drive, floppy disk, or CD-ROM.
What is virus in simple words?
A virus is a small infectious agent that replicates inside living cells. Viruses can cause serious illnesses in humans, animals, and plants.
Viruses are made up of genetic material, either DNA or RNA, inside a protein coat. They are too small to be seen with a regular microscope. They can be identified by their unique shapes.
Viruses are found everywhere in the environment. They can be carried by water, air, and soil. They can also be carried by animals and insects.
Viruses can cause a wide range of illnesses in humans, animals, and plants. Some common viral diseases are the common cold, the flu, chickenpox, and Ebola.
There is no cure for most viral diseases. Treatment is focused on relieving symptoms and supporting the body’s immune system.
Viruses are a major cause of death around the world. They are responsible for millions of deaths each year. Many of these deaths are in developing countries where people do not have access to health care.
There is no vaccine against all viruses. Some common vaccines against viral diseases are the MMR (mumps, measles, rubella) vaccine, the flu vaccine, and the HPV (human papillomavirus) vaccine.
Viruses are a major cause of concern for public health officials. They are a leading cause of epidemics and pandemics. An epidemic is a widespread outbreak of a disease. A pandemic is a worldwide outbreak of a disease.
Viruses are a major challenge for scientists who are working to develop new treatments and vaccines. They are difficult to study because they are so small and their genetic material is difficult to sequence.
What is first computer virus?
The first computer virus was created in the early 1980s by a programmer in the US who is known by the pseudonym, ‘John von Neumann’. The virus, which was also called ‘Virus 1.0’, was designed to attack the operating system of early IBM PCs.
The virus was spread by copying itself from one computer to another when users connected their PCs to a shared network. It would then hide in the memory of the computer, and would activate each time the computer was turned on, causing it to crash.
Virus 1.0 was not very sophisticated, and it was quickly defeated by anti-virus software. However, it was the first example of a computer virus, and it showed the potential for these programs to cause damage and disruption.
Since then, computer viruses have become more sophisticated and dangerous, and they continue to pose a threat to businesses and individuals around the world.

What is computer virus name its example?
A computer virus is a type of malicious software that, once installed on a computer, can replicate itself and spread to other computers. It can cause extensive damage to the computer system and data stored on it.
One of the most common types of computer viruses is the worm. A worm is a self-replicating virus that spreads through computer networks. It can cause the network to slow down or even crash.
Another common type of computer virus is the Trojan horse. A Trojan horse is a program that masquerades as something else, such as a game or a picture, in order to trick users into installing it on their computer. Once installed, it can steal data or damage the computer.
There are many other types of computer viruses, including file infectors, boot sector viruses, and macro viruses.
The best way to protect your computer from viruses is to install antivirus software and keep it up-to-date. You should also be careful about what programs you install and where you download them from.
