Explanation of virus:

1) Virus is a small program that its activity can destruct/destroy
some files and a computer system. If you don not open this program, it's still
inactive and could not destroy anything.

2) The virus program brought to you by an email as attachment from spammer or
known as cracker. It has a server itself (virus server).
Virus attachment cannot go into another email to become attachment the another
email, such as an email was sent by user (netter), members of group, moderator
etc. It must be brought to you by email virus itself, that's why, we called them
VIRUS EMAIL or SPAM EMAIL.

3) VIRUS EMAIL would be sent by any email address of any account, because
the sender always search and catch email address in boxes FROM, TO: and CC:
of sending email including from user's address book.
They search to found out then copy or cracked some addresses, even some sending
email included its subject line, from mailbox of users' anywhere.
So that why the virus email looks like was sent by our friend, our member,
our moderator etc..... may be able even by your own email address.

4) How to identification of virus attachment:
it has a small size ( 181-285 KB )
it has extension file name such as below (don't open it):
*.scr
*.pif
*.zip
*.HQX
*.MQX
*.mim
*.bat
*.exe
*.com
*.txt
*.doc
*.clp
*.lhz
*.rhz
and more other new extension name files,
and some time it appears as the compressed file... *.zip file.
Also by a fake name like this: HotMovie.MPEG_ _________ scr.
actually that file is virus file with extension .scr
Be aware, safe to be safe is only open *.JPG file.

Subject email virus.
5) By having experience you could identified an email virus from their SUBJECT,
most of them contains an amazing statement or unusual word,
such as the following examples (don't open it):

and more, and more...and in this year
virus type of warm was able to copy your sending email included subject line,
but the copied email consist of virus attachment.
When you received emails with that subject matter, delete it straight away.
Don't open it any more, otherwise the virus sender will see that your account is still active.
NOTE:
So, if you write an email, don't make a subject line with words look like VIRUS EMAIL otherwise your email will be deleted by recipient.

CAUTION: it's dangerous.
*** If one of your files has an infected virus, then you open or accessed the infected file, it could infect other files and then all files in your hard drive
*** Don't open or reply virus email so that they cannot see you still active.
