Excite@Home to offer McAfee Personal Firewall service to Excite@Home customers in @Home Online Safety Area
SANTA CLARA, Calif., January 31, 2000 -- McAfee.com (Nasdaq: MCAF), the leading global consumer Application Service Provider (ASP) of online PC security and management services, announced today that it has agreed to acquire Canada-based Signal9 Solutions Canada Inc. The $18 million transaction, comprised of cash and McAfee.com Class A Common Stock, is expected to close within the next several weeks.

Signal9's award-winning products, ConSeal Private Desktop and ConSeal PC Firewall will be incorporated into the McAfee.com services lineup later this quarter. ConSeal Private Desktop is a personal firewall that offers comprehensive security control of the PC connection to the Internet. Designed for the non-technical user, it prevents hackers and crackers from accessing personal computer files, running Trojan attacks or crashing a system. It blocks all known attacks found on the Internet, including Back Orifice, Netbus, denial of service and cyberstalkers.

"Consumers are becoming increasingly very aware of the various threats posed by malicious behavior on the Internet, " said McAfee.com President and CEO Srivats Sampath. "We are now adding personal firewall services that will protect the consumer from hackers, in much the same way our anti-virus services protect the consumer from malicious computer code in the form of viruses."

The acquisition enables the incorporation of Signal9's products into the McAfee.com services line-up under the name McAfee Personal Firewall. Signal9 senior engineering staff will join McAfee.com in their Santa Clara offices and will be active participants in developing the next generation of security products for consumers. Signal9 staff joining McAfee.com will also provide ongoing support for existing Signal9 customers.

Excite@Home to offer McAfee Personal Firewall
In a separate announcement today, Excite@Home (Nasdaq: ATHM), and McAfee.com have partnered to provide McAfee.com security services to the Excite@Home user base. The security tools will be integrated into the @Home Online Safety Area and bring key functionality, including a free 90-day trial of the new McAfee Personal Firewall.

McAfee.com Personal Firewall will protect users of both dial-up and broadband Internet services. Broadband connectivity - in the form of DSL or cable modem services - can be more risky because of its "always-on" connection feature, leaving users open to potential hackers on an around the clock basis. Broadband adoption rates - in both DSL and cable modems - are expected to soar in the coming years. Forrester Research predicts that more than 26 million people will subscribe to broadband services by the year 2003.

Firewalls protect consumers from hackers and other unwanted activities directed at their PCs. The McAfee Personal Firewall is a consumer-friendly, ready to use product that will allow the non-technically savvy user to provide state of the art protection against hackers and malicious code on the Internet.
