Antivirus software

Computer viruses pose significant threats to the security and efficient running of both stand-alone computers and networks. They can disclose user passwords, steal information, destroy data, install "back doors" to let hackers in, clog print queues, disrupt Internet traffic, overload email servers - and new threats appear daily.

It is crucial that both network servers and workstations are always running reputable virus scanners using up-to-date virus definitions. Using old virus definitions is worse than using no virus scanning at all, since computers are vulnerable while their users work under the misapprehension that they are safely protected.
