How is
virus activated on your computers?
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.
