Abstract:
An email virus makes use of the email technology and
attaches itself to an email to transfer itself from one computer to another.
Some email viruses create and send new emails using the address book of the
victim computer. The email viruses are a matter of concern as they can spread
very fast via emails to different geographical locations.
The conventional scanners are file based and not good for
scanning emails as the emails can contain different types of files as
attachments. Besides they cannot detect viruses until the emails are downloaded
and opened by the recipient in order to be scanned in the receiver’s machine.
Scanning emails on the email servers is difficult as the emails on email
servers are encrypted for privacy purposes and not accessible to virus
scanners. Besides, detecting virus emails is confusing as they often originate
from genuine addresses.
The advanced virus scanners use various special techniques
to scan the emails at various stages on the way before the infected mails can
reach the recipient. The advanced methods not only deal with email virus
detection and removal but also detect and control the outbreaks of email
viruses.
