There are different methods

through viruses may be transferred from one

computer to another.

Now- a-days,

most of the viruses spread due to receiving

unknown e-mail messages that contains viruses.

When a user opens such an infected message, the

virus is also loaded into the computer memory.

In this way, many other program files loaded

into the memory are infected. This virus is also

transferred to other computers when e-mail

messages are sent from the infected computer to

them. Due to these viruses, some time an auto

generated email message from your email ID sends

to your friends from your side with different

virus messages. Never open unknown and

attractive subject line email messages, always

scan first even if you know the sender of the

message. 

Another way of

spreading virus is by using Internet and other

networks. For example, when you download

infected executables files or data files from

the Internet or from a shared disk on the

network, viruses are transferred to your

computer. It must be noted that many software

are available on the Internet with free of cost.

Most of that software contains viruses, for

example free PHP or ASP scripts are the main

source of virus, always get these scripts from

reliable sources. In an LAN, if a computer

contains a virus, then all the computers on the

network may be infected with that virus.   



One important means of exchanging

data is through the use of removable media like,

CDs, MP3 player, ipod and flash devices. So,

when you copy the data from one computer to

another by using a removable media, the viruses

are also transferred. 

The

virus can also infect your computer by using

pirated software. The software, which is

installed into your computer without license is

referred to as pirated software. Some companies

may intentionally attach some virus programs

into their software. This program will only

activate when it does not find some special

files like license files on your computer.
