Microsoft Forefront anti-virus software (UTSA-owned Windows-based computers)

McAfee VirusScan anti-virus software (for Windows-based computers) was replaced in March 2010 with Microsoft Forefront Anti-Virus. Microsoft Forefront displays your PC system health using a set of icons. The color of the icon denotes the status of virus checking on your PC.

Status Good / Scan in Progress. The first icon signifies that no threats have been identified. The second icon shows that your PC is currently being scanned. There is no need to contact OITConnect if you see either of these icons.

Anti-virus Software for Macintosh Computers

Step One: Uninstall previous anti-virus software:

UTSA Macintosh users should uninstall McAfee VirusScan or Virex from their system by August 2010, as the McAfee site license will expire on August 31.

If you have VirusScan or Virex anti-virus software present on your Mac, you can download uninstallers for both Virex and VirusScan by downloading the uninstaller disk image (DMG).

Please contact OITConnect, 458-5555, for assistance.
