    Some Network Associates Inc. customers are up in arms over an update
    for one of the company's antivirus products that is preventing them
    from accessing the Internet.
    The problem is caused by an update for McAfee VirusScan Professional
    7.0, the company's flagship enterprise antivirus application. When
    update 7.03 is installed on some machines running Windows 2000 or
    Windows XP, it prevents the PCs from connecting to the Internet after
    the suggested reboot. The problem seems to be affecting customers who
    upgraded from 7.02 to 7.03.
    McAfee has pulled the update from its download servers and is
    performing quality checks on it, according to information on the
    company's Web site, but has not provided customers with any
    instructions on how to fix affected machines.
    "I am so angry with these people it's palpable. I write software and
    cannot believe they released a patch before thoroughly testing it,"  
    said Michael Shohoney, a VirusScan user who said his PC was down for
    more than six hours before he was able to restore the Internet
    A spokeswoman at NAI, based in Santa Clara, Calif., said she was
    unaware of the problem and would look into it.
    Some users report that uninstalling the troublesome patch and
    reverting to the last known good version of VirusScan restores their
    Internet connectivity. However, others say this hasn't worked for
    A McAfee technical support representative writing in the site's help
    forums said that the company believes the problem lies in a DLL that
    controls the Hostile Activity Watch Kernel (HAWK), a feature that
    looks for malicious and "virus-like" behavior.
