Google w32.Allaple.Gen shows many entries for this worm.

If possible, use Virus Total dot com to scan with 40+ viruses and post your link results here. Upload the file directly off the install cd to: https://www.virustotal.com/ and click scan.

It is possible this is a false positive. One way to determine that is to do the above.

Webroot seems to have blocked the installation of the file, if so, you should not see it on your hard drive.

Another tactic is to wait a couple of days for the virus database to progress forward, and see if scanning your cd produces the same result. Files on the cd are read-only and cannot become active until read or installed on your hard drive.

You can also post on the Webroot forum for help with this there.
