Abstract
The field of information technology is growing very quickly, and so there are more and more regular updates. At the same time, computer viruses are also on the increase, and people are now even complaining that attacks on computers are mostly from within the intranet structure. So, if we are able to update the signature files of the anti-virus software that exists on the various computers that are used by the various members of the locality concerned, we can prevent the problems of viruses to some extent. In order to do this, nowadays, system administrators send reminders to the people concerned, or else the computers have to be set to update every few days or so. These systems have their own drawbacks. To avoid this hazard, we provide an option for active packet-oriented automatic signature file updating.
