To learn more about viruses, what they are, and how they work, you might read "Frequently Asked Questions on Virus-L/comp.virus" at www.bocklabs.wisc.edu/~janda/virl_faq.html. You'll find additional virus FAQs and many practical tips in the Windows magazine online article, "WinFAQ: PC Viruses-Here's What You Need to Know About Viruses-and How to Keep Your System Safe" by Lenny Bailes (www.techweb.com/se/directlink.cgi?WIN19980101S0101). You can find information about the latest viruses, including descriptions of specific virus payloads at Symantec's AntiVirus Research Center at www.symantec.com/avcenter/index.html and at Network Associates' Virus Information Center at vil.nai.com/villib/alpha.asp. The ICSA Lab publishes an annual survey of virus attacks. The 1999 survey is available at www.icsa.net/html/library/whitepapers/index.shtml (click INFOSEC: Year in Review; you will need the Acrobat Reader). For a taste of the virus problems that face network managers, check out the article "Trend InterScan Secures Top Virus-Protection Spot" by Jeffrey H. Rubin and Timothy M. O'Shea in the April 5, 1999, issue of Network Computing magazine (also on the Web at www.techweb.com/se/directlink.cgi?NWC19990405S0018). Some virus reports are hoaxes. Check the site www.nonprofit.net/hoax/hoax.html before you panic and spread information about a fake virus. You can also connect to the F-Secure Corporation (formerly Data Fellows) site at www.f-secure.com/virus-info/ (formerly www.datafellows.com/virus-info), which maintains a database of viruses and up-to-date information on virus hoaxes.
