What is Virus !
The full form of VIRUS is Vital Information Resources Under Siege. Viruses are small programs in the computer. Those which enter the computer and affect the functioning of the computer are called viruses. In simple words, a computer virus is a harmful software program which destroys the data of the computer badly.
Once the virus enters the computer, it automatically spreads throughout the computer and corrupts all the programs present in the computer. The job of the virus is to steal the computer's data, damage the data and modify the data. The virus has the ability to generate its own copy due to which it spreads easily from one computer to another.
A virus is a malicious program that damages the computer's data. It works to erase or spoil the computer data. The virus is a program written intentionally. It attaches itself to the computer's boot and the more the computer boots, the more the virus spreads. The virus slows down the speed of the hard disk by entering the boot sector of the hard disk and can also stop the program from running. Many viruses can damage data and programs even after a long time. The virus associated with any program does not become active until the program is run. When the virus becomes active, it attaches itself to the computer memory and starts spreading.
Symptoms Of A Computer Virus
Program virus affects the program file. Boot virus affects the boot record, partition and allocation table. There can be many reasons for the spread of virus in a computer. Infected floppy disk, infected CD or infected pen drive etc. are helpful in spreading the virus. Virus can also spread in the computer through e-mail, games, internet files. It is not very difficult to identify the virus. Before the virus infection takes a serious form, its symptoms are visible in the computer which are as follows.
When The Computer is Slow
If the computer has become very slow and is taking a lot of time to open any software, it means that a large part of its memory and CPU is busy processing the virus or spyware. In such a situation, it takes time for the computer to start and for the web pages to open on Internet Explorer.
Changes To Browser Settings
If the homepage of your browser has changed automatically, then it is quite possible that your computer has been attacked by some spyware. Homepage is the website or web page that opens automatically when you start the internet browser.
Usually we set our homepage from the Tools menu, which is usually your favorite website, search engine or most used services like email etc.Spyware installed in the PC changes this to take you to a specific website.
Computer Hanging
When the computer starts jamming or suddenly hanging repeatedly, understand that it may be due to infection. Especially if you have not installed any new software or hardware in the computer.
Pop Up Windows
As soon as you start the internet browser, many types of pop-up windows start opening one after the other. It is possible that some of these may be advertising a particular thing or website, or they may be filled with links to pornographic websites.
When Weird icons Start Appearing
Strange icons may have appeared on your desktop or system tray, even though you have not installed any such software. When clicked, they quickly open pornographic websites.
Unknown Folders And Files
Some folders appear on any drive or desktop of your computer which you did not create. There are some files inside them which were neither created by you nor were they created by the installation of any software. Apart from this, even after deleting them, they appear again after some time.

When a user opens his computer, some programs open automatically which are called unwanted programs. This also happens due to a virus.
