What is a computer virus?In: Computer Viruses |
[Edit] |
Answer
A computer "virus" is a program that runs on your computer doing things you would not want it to do. Typically, this will involve doing damage to your hard-drive, or sending mail without your permission. A virus gets onto your computer usually when you connect to the internet. Browsing the internet sometimes calls for small programs to be downloaded to your computer, and they run there to help make the whole thing you are looking at go quicker or easier. Some of these, however have been put there to drop a little "extra" program onto your system, which will then deliberately mess things up. You can sometimes have a virus that hasn't yet hurt anything, but is waiting for a moment or date in time when it will be activated. The best way to insure that you don't have a virus is to buy virus scan software, have it on your system, and have it scanning your system periodically. Virus scan software can delete virus's automatically, and prevent new ones from getting onto your system.
