Computer Viruses
In recent years, the explosion in the use of networks and the Internet has created a new avenue for computer viruses to spread at a rapid rate. Earlier viruses used executable files and would typically be no more than an annoyance by displaying harmless phrases. The latest viruses are much more sophisticated and able to cause extensive and irreparable damage to files. Some viruses are able to spread themselves to other computers on the Internet or network causing widespread damage to many systems.What is a computer virus? A virus is a piece of software designed and written to adversely affect your computer by altering the way it works without your knowledge or permission. In more technical terms, a virus is a segment of program code that attaches itself to one of your executable files and spreads systematically from one file to another. Computer viruses do not spontaneously generate. They must be written and have a specific purpose. A computer virus (virus) is a program that invades computer systems and performs a variety of damaging tasks after a "trigger" event occurs. The "trigger" event can be as simple as starting up a word processing program or opening an e-mail attachment from an e-mail cl
If you do not know the sender, or if you know the sender but have are not actually expecting to receive an attachment from them you MUST NOT open the attachment, by double clicking on it or in any other way. It infects entire networks of computers by making a copy of itself as it moves from system to system. Some of the most popular ant-virus software is Norton and McAffe ant-virus programs. What kind of damage can it cause? A benign virus is one that is designed to do no real damage to your computer. Some of the more malignant viruses will erase your entire hard disk, or delete files. Be sure to install an anti-virus software program to guard against virus attacks. These are just some recent viruses to name a few. This means that you must be very suspicious of ALL attachments, and should closely scrutinize the message that accompanies the attachment. Computer viruses spread by attaching themselves to another program (such as your word processing or spreadsheet programs) or to the boot sector of a diskette. Victims are falsely lured into thinking that their computer systems will benefit from the infected program when in reality, the Trojan horse is waiting for a "trigger" event to occur so that it can activate its damaging behavior. Do not open e-mail attachments if you do not recognize the sender. The virus is in the attachment, which is an executable file called fix20001. This bootable floppy disk should have the anti-virus software scanner on it and other necessary files for the scanner to work. Report new viruses immediately to your anti-virus software vendor.
