If a virus enters into the computer, it links up with a software which is already installed. When we execute the infected program, the virus starts functioning. There are virus softwares which function only on a specific date. The virus Friday thirteenth functions only when the date is 13 and day becomes Friday. Another virus Michelangelo functions on March 6, the birthday of the great artist, Michel Angelo.
The viruses are divided into many different categories. One type links with the program and start functioning when the infected software is executed. Another type enters into the boot sector of the hard disk and starts functioning while booting the computer.
The only way to get rid of the virus is by using an anti-virus program. These programs search through the floppy disk, compact disk, hard disk etc. and destroy the viruses. These softwares are very costly. The following steps may help to prevent the virus from entering into our computer.

2. Install the best anti-virus software available in the market and update with latest version frequently.
3. Scan before using disks from outside and make sure that they are not infected by virus.
Some anti-virus softwares reside in the memory and inform us the presence of virus while using an infected disk.
4. Before opening an e-mail, make sure that the attachment of the e-mail is not infected.
To reduce the loss of data or software, back up the data or software frequently. This helps us to restore them from the back up. To make back up, always use CDs / DVDs which are more durable these days.
It is better for the business people who are using computers for accounting to keep hard copies (print outs).
Always scan the hard disk using anti-virus softwares. If a virus is found, use the most powerful anti-virus softwares to destroy it.

Day by day new viruses are generated. The damage caused by the virus "I Love You" and "Melisa" were huge as you have already known
