So I erased all of the messages without opening them. I went about my work. If your company wants to avoid losing irreplaceable data and spending untold hours rebuilding its computer systems, it must address three areas. First, understand the limits of current enterprise design. Firewalls and anti-virus software can't catch everything.
People can write viruses more quickly than security companies can write protective software.
In the first day or two of a virus's life, you're probably not protected. Second, understand the limits of your company's applications. If you must use Microsoft Outlook for e-mail, for example, then at least make sure that you understand its vulnerabilities. Until recently, Outlook came from Microsoft set to run any script it received automatically, so the creator of a virus had only to encapsulate it in a VBS container for the virus to load and run. Other e-mail clients avoid this vulnerability.
