What’s a Computer Virus?
Computer viruses are undesirable computer programs that can invade your hard drive and cause several unique kinds of damage. Usually, viruses are created whenever someone writes a computer program and embeds harmful applications within that program. As soon as other men and women start downloading that infected program onto their computers, the virus finds it’s way in and negatively affects information stored in the computers. Not one computer virus is equally, there are countless diverse programs that cause varying amounts of damage to a computer.
The same as human viruses, computer viruses spread quickly as soon they’re created and computers are vulnerable to the’disease’. Although rather than traveling through the atmosphere, computer viruses disperse themselves all over the internet, there are times when you can get a virus by simply clicking on a specific webpage. Many times computer users are going to have virus in their computer for a long time period before it’s detected or before it begins causing greater damage. Even once you have antivirus applications on your computer, it won’t always find every virus since the antivirus software can only find dangers known through that program’s database.
You might ask, Why would someone create such counterproductive applications?
Well, there might not be an exact answer as to why humans knowingly create computer viruses besides to find some type of revenge or to challenge their skills. Nobody will have the ability to prevent those individuals from creating viruses and exposing different computers to disease, the best thing for computer users to do to prevent such invasion would be to utilize current antivirus applications and be cautious about what websites they visit and what files they download.
When a virus finds it’s way into your computer, it is going to hide in your hard disk and rapidly replicate itself like virus cells perform in humans. You might not be able to tell, but each time you save your information, you’re also saving the virus. Soon enough the virus has multiplied to such a wonderful extent that it hurts your data and causes significant issues.
Even though the computer’s ROM (Read Only Memory) won’t be affected by a virus, the RAM (Random Access Memory) along with your computer’s disks will definitely be damaged. Therefore, if the virus is only in the RAM data on your computer when you shut the computer down the virus will be lost in addition to any other memory that was stored in the random access memory (RAM).
Regrettably, if the computer virus is on your hard disk or computer disc it will stay in the computer after you restart it and it is going to be there whenever you use the application. If you change from the infected program into another program without shutting down your computer, the virus will then attach to another program. With that happening, that virus will gradually undergo infecting all your computer’s programs before you’ve got a clue that your computer is infected.
At present, millions and millions of dollars are spent on attempts to protect computers from viruses and remove destructive virus programs.
Antivirus programs provided by commercial and shareware resources were created solely to detect and fix programs that may be virus infected. These programs should be used to scan for viruses each time you place a disk on your computer and every time you start up your computer.
