Computer Virus

Computer technology has developed rapidly. New hardware and software have competed with one another. The vendors try hard to please the users and to fulfill their needs. Meanwhile, new viruses also emerge. They are ready to attack computers.

What are viruses? According to Microsoft (www.microsoft.com), computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk. Viruses are most easily spread by attachments in e-mail messages or instant messaging messages. That is why it is essential that you never open e-mail attachments unless you know who it's from and you are expecting it. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download.

Considering the bad effects caused by a virus, we must always be careful and always take a preventive action. Install an antivirus program in your computer and update it regularly.
But you must also keep in your mind that installing an antivirus program does not guarantee 100% that your computer is free from viruses.
