You mean, so most of us who work in companies that have computer systems, it runs a sort of computer virus program. The antivirus industry is a reactive industry. We find a malicious bit of code and we find a way of detecting it and curing it, and we distribute that patch, that update to all of our customers. There's a lot of different ways of distributing it. Sometimes it tells the users, sometimes it doesn't.
Some products require the users to go up to the vendor's web site and to download the latest patch.
It's a lot of different technologies. The point is that it's reactive. And a lot of end users, a lot of people don't have time or the knowledge to go and update the virus protection products. Well, right now really it's a good idea to stay away from file attachments. I mean, you really have to make sure that if someone sends you something that you expect to get it.
