Cheyenne Software has introduced three utilities to keep your PC in tip-top shape. They can add to your computer's memory, serve as insurance against lost data and improve your system's overall health. Cheyenne Infinite Disk can free up hard disk space, Cheyenne Backup recovers lost data and Cheyenne AntiVirus protects against viruses.

Infinite Disk was acquired by Cheyenne from Chili Pepper Software. The new version frees hard disk space by uninstalling infrequently used files and applications and compressing them into a secondary storage.

Backup is a single-disk data recovery solution. It can reinstall lost data, recover your operating system, and back up and restore program or other important information. It detects virus-infected files during backup. AntiVirus analyzes and develops remedies for the latest viruses. It integrates with Windows 95's Explorer and includes a macro virus analyzer.

Infinite Disk and Backup, $79 each; AntiVirus, $69
