I too had Avast! give a Trojan warning during Shozam! installation. The message left in the Avast! log file reads:
3/25/2007 5:53:17 PM SYSTEM 1972 Sign of "Win32:Inject-BD [Trj]" has been found in "D:\Shozam!\KResource.dll" file.
I aborted the installation, deleted the downloaded file, figuring that if the KRsource.dll had a Trojan-like signature prior to being installed, Shozam! was not a program I wanted resident on my machine. Any thoughts on why the KResource.dll file would display a Trojan-like signature when scanned by Avast! during the installation process?
I run my machine on an AMD dual-core 64-bit processor and have it in a dual-boot configuration. I only tried installation when booted with the 32 bit XP pro mode. I may try an installation on the 64 bit XP-Pro boot later and will let you know the results. Both boot versions use Avast! as the anti-virus protection. I have installed and used Web Gallery Wizard PRO on both the 32 and 64 bit boots.
Thanks.
