Santa Monica, Calif., July 29, 1998 --
CyberMedia, Inc. (NASDAQ:CYBR), today announced that Guard Dog™ Deluxe, the first comprehensive personal Internet privacy and security software product designed for Microsoft Windows® 95 and Windows 98 users was listed as the 10th best selling business software program for the month of June. This marks the first time Guard Dog has been ranked in the top ten since it was originally introduced in October, 1997.

"We are delighted that Guard Dog has been able to make the Top Ten so rapidly," said Tim Petras, CyberMedia's Manager of privacy and security products. "Privacy and identity theft are serious concerns for today's Internet users and this is a testimony that Guard Dog effectively addresses such concerns."

Guard Dog Deluxe Protects Users Privacy on the Internet
CyberMedia created Guard Dog Deluxe to protect Internet users against privacy, security and virus threats. An Internet Guardian works in the background continually monitoring individual Internet sessions for potentially harmful threats. It notifies a user of any attack or intrusion with a barking sound much like a real live "guard dog" would.

Guard Dog Deluxe automatically blocks unwanted "cookies" that can be used to monitor a user's Web browsing habits and guards against hostile ActiveX controls that can delete data files, corrupt hard drives or steal sensitive information. Guard Dog Deluxe also includes full anti-virus protection based on technology licensed from Trend Micro.

Guard Dog Deluxe protects PC users by building a personal "firewall" around critical and sensitive files, such as passwords and financial records. It allows permitted applications to access the files, but blocks attempts by unauthorized ones.

Unlike traditional anti-virus software, which uses a pre-installed database of virus "signatures" to detect invasions, Guard Dog Deluxe's approach enables it to continually detect new or unknown attacks.

Guard Dog Deluxe:

• Stops unwanted cookies so a user's actions are not tracked
• Blocks hostile ActiveX Controls that can damage a user's PC
• Blocks search requests and other data entered at a Web site from being forwarded silently to other sites
• Monitors all programs and applets for suspicious behavior
• Cleans up trails left behind as users surf the Web
• Protects sensitive information, such as e-mail files, passwords, and other personal data so any unauthorized program does not access it
• Includes full anti-virus protection

Runs on any IBM or 100-percent compatible 486 or higher PC. Requires Windows 95 or Windows 98, 8 MB RAM minimum, a hard drive with a minimum of 6 MB free disk space, 256-color VGA monitor and an existing Internet connection.
