Virus detection

Virus-checking programs are indispensable to any network security solution. Virus checkers monitor computers and look for malicious code. One problem with virus checkers is that one must install them on all computers for maximum effectiveness. It is time-consuming to install the software and requires updating monthly for maximum effectiveness. Users can be trained to perform these updates but they can not be relied upon. In addition to the normal virus checking on each computer, we recommend that organizations scan e-mail attachments at the e-mail server. This way, the majority of viruses are stopped before ever reaching the users.
