Features such as Guard Dog and File Transporter for Palm Enhance Wireless Security Center Offerings

SUNNYVALE, Calif. - September 5, 2000 — McAfee.com (NASDAQ: MCAF), a leading global consumer Application Service Provider (ASP) of PC security and management services, today announced the availability of application monitoring software and other applications for the Internet's only service to protect, manage and maintain handheld devices running on the Palm OS, Pocket PC (Windows CE) and EPOC operating systems. The new applications offer McAfee.com's Wireless Security Center users enhanced anti-virus and handheld file management services for the most common wireless platforms.

McAfee.com Guard Dog for Palm

Based on the popular Guard Dog security program for the PC, McAfee.com Guard Dog for Palm prevents users from unknowingly allowing rogue applications to view, steal or delete data from their Palm devices. The program lets users decide what applications are trustworthy and prevents those that are not from accessing the sensitive information that resides on these handheld devices.

Guard Dog for Palm continuously monitors the device, searching for specific actions and immediately notifying the user of any strange or malicious behavior including:

• Application launches
• Infrared beaming
• Power on/off events
• Database and record creation/deletion
• Password monitoring
• Preferences changes

Additional New Wireless Security Center Applications

In addition to Guard Dog for Palm, McAfee.com is also releasing two new file and system management tools for the wireless device market.

• File Transporter for Palm — File Transporter can be used to transfer files like a resume, a business card or even product code from PC to PC or PC to PDA. Users may now package information and take it with them. Presently, many Palm applications convert PC files to the Palm file system before storing the information. The File Transporter circumvents this lengthy process by using a specially designed "wrapper" for PC files. The user simply wraps the file and adds it to the device; unwrapping is just as easy.
  
• Performance Optimizer for Windows CE / Pocket PC — Improves memory usage and access to data. This application brings Performance Optimizer, the McAfee.com system maintenance application, to Windows CE and Pocket PC devices. The program scans the handheld device components, checks for problems, and offers automatic fixes when available.

"Recent events have illustrated the need for consumers to consider the security aspect of any device that connects to the Internet-including the PDA," said Patti Dock, vice president of marketing, McAfee.com. "Consumers want increased security for these handheld devices, but not at the expense of the flexibility the devices provide. Guard Dog for Palm will allow subscribers to have the best of both worlds."

McAfee.com's Guard Dog for Palm is among the first products designed specifically to protect the growing handheld market-a market some analysts project will skyrocket from today's 10 million users to ten times that by the year 2003, surpassing the number of desktop PCs sold annually. Along the way, these new users will increase U.S. mobile-commerce services from $90 million at the end of this year to $1.2 billion in 2005, according to a report released by market analyst Datamonitor.
