False Positive related to Lord of the Rings game?

using Avast 4.8.1229 with VPS v.080727-0 on WinXP SP2.

Pick up the following virus warnings while doing a weekly scan.
Sign of “Win32:Trojan-gen {Other}” has been found in “C:\WINDOWS\Installer\34acdd5.msp\PCW_CAB_Family0\Fellowship.exe[Embedded#202e0b]” file.
Sign of “Win32:Trojan-gen {Other}” has been found in “C:\WINDOWS\Installer\34ace08.msp\PCW_CAB_Family0\Fellowship.exe[Embedded#202e0b]” file.

Both files cannot be moved to the virus chest probably because the size is too big, about 20MB each. Nevertheless using 7-zip, I manage to extract the offending file, Fellowship.exe which is related to the Lord of the Rings: The Fellowship of the Ring game I’ve uninstalled a long time ago, and upload to virustotal with the following results.

I also did a SUPERAntiSpyware scan which showed no virus warning.

Please advise on the next course of action. Should I send the 20MB msp files to virus@avast.com or the 2MB Fellowship.exe instead? Is it safe to delete the ‘infected’ msp files from my Windows’ Installer folder since I’ve uninstalled the game a long time ago? Thank for the help.

False positive. Yes, you can send it to avast!
