4. The gateway to security is to apply quality security software
on your computers as preventive measure towards protecting
your work and sensitive data from falling prey to the malice.
When security is at stake owing to viruses, spyware, and
other security threats, quality security cannot have a
substitute. Getting good anti-virus software installed is
necessary to avoid risking all of your work or sensitive data
that might get compromised. Antivirus protections help your
system with effective virus scan & removal, but then we
indeed need to implement few measures specifically on our
part. For this:

6. Let us discuss some strange email notifications that can often
prove to be harmful. At times you might receive notices
saying that emails sent by you were not delivered, when you
are unaware of having sent one. Such are the strange
situations that viruses endow you with. This kind of virus
sends mail from somebody else’s PCs, though the mails
resemble as if sent from you or vice-versa. Such malicious
activity of virus is called spoofing of the 'from address'.

7. It is both annoying and unusual that in spite of your system
protected by strong antivirus, virus on someone else’s
computer that is sending such emails out in the ploy of , there
is someone else out there whose computer is infected and

8. See how the virus spoofs the from-address in emails:
• Efficient anti-virus software installed on your computer to
keep it safe,
• You happen to send an e-mail to a Friend,
• Now your email address gets registered in your Friend’s
address book within his email software,
• Your Friend happens to have not so effective anti-virus
software, and his PC is virus infected,
• The virus infesting your Friend’s computer scans through
his address book to fetch all the email addresses on it,

9. • Now the virus starts its activities by sending e-mails to all
the addresses on your Friend’s address book,
• But then these virus e-mails do not specify that they are
from your Friend. Rather it opts another address from your
Friend's address book and enters it within the 'From field' of
the outgoing email.
• This virus may mingle the name of one address and the
domain of the other, thereby creating a 'from address' that
never exists.
• These emails when received by other PC with effective anti-
virus software s, instantly the virus gets detected and the
email gets rejected,

10. • On rejecting the virus fed mail, the receiving computer, it
sends an 'Undeliverable' message to the sender. Su8ch as:
'Subject: /Delivery Notification: Delivery has failed'.
• But then this message doesn’t go to your friend, and instead
goes to the spoofed address. It can rather be sent to you.
• At time you would not find your Friend’s genuine address
in the virus stuffed email or the 'Undeliverable' note, hence
you remain unsure about the real virus email sending
computer or sender.
