Virus
has divastating effect on the web world. It shows our vulnerability and interconnectivity
in the web world. Virus is sometimes Called Vital Information Resources under
the system.
Virus
is a little program that its activity can destroy some files and a computer
system. If you don’t open this program, it still inactive and could not destroy
anything.
The
virus program bought to you by an e-mail as attachment. It has a server itself (virus
Server). Virus file attachment can’t go another there e-mail itself, that me
called virus E-mail a spam.
Virus
EMAIL would be sent by an e-mail address of any account that they found and
cracked from some mailbox or address book of users from anywhere and
identification of virus attachment has a small size (181-285 KB):-
It
has extension file name such as below (don’t open it):
*. Scr
/ *. Clp / *. Pif/ *. bat/ *.exe/ *.com/ *. Txt / *.doc / * lhz/ *.rhz and some
time it’s compressed by *. Zip file also by a fake name like this hot movie.
MPEG_Scr.
Actually that file is virus file with extension .Scr
You
could identify an e-mail virus forms their subject most of them contains an
amazing statement or unusual words viz. the following examples (don’t open it):

and
more & more... When you received e-mails with the subject matter as said
above delete it straight away. Don’t open it anymore. Otherwise the virus
sender see that your account still active.
Earlier
viruses were pieces of programs attached to common programs like a popular game
or world processor.
A
person might download an infected game from a bulletin board and run.
A
virus is thus a small piece embedded in large program. It runs only when the
legitimate program is executed. This is how virus spreads. Virus creators got
more sophiscated by using tricks like loading virus on the memory so that they
could keep it running in the background till the system remains on or infecting
the boot sector of the floppy disks and hard disks.
In
general both executable and boot sector virus are not threatening any more as
nearly every program comes on compact disc when are invulnerable by viral
infection. You should use secure operating system like Linux, Solaris, and
Windows Vista. If you are using unsecured operating system then buying virus – protecting
software is a nice safeguard.
Also disable the Compact disk booting (i.e.
CD-Rom/ CD-Writer / DVD-ROM/ DVD writer to eliminate the risk of boot sector virtues
coming in from pen-drive / MMC / Compact disks left in the drive. So, e-mail attachments
in .DOC, .XLS, .GIF, .JPG are data files can do no damage to the computer like
.EXE, .COM, .VBS are executable. Such files can do any damages once executed.
Hence the only protect is never run executables that arrive via e-mail.
Please
do always remember: Don’t make subject e-mail contains word looks like VIRUS
EMAIL. Otherwise your e-mail would be deleted by recipient [S]
