Software/Versions Affected:

When you are running Norton AntiVirus™ software and you are using the virus definition file of 9 November 2001, a FALSE virus alert (w32nimda virus) may be triggered when installing Optics.

This virus definition file provided by Symantec incorrectly identified the InstallShield Professional 6.31 script engine (ikernel.exe) as being infected by the W32.Nimda.enc (dr) virus. This is a false positive. Symantec has already updated their virus definition files. If you encounter this problem, please update your Norton AntiVirus™ definition file.
