Nero Photoshow 5 - Virus Alert?!@

Just bought a new HP laptop running Vista Premium and Avira Anti-Virus and got virus/trojan alert prior to installation of Nero PhotoShow Deluxe 5 from CD sent to me from Nero (backup CD since software was originally downloaded from Nero):

“E:\setup.exe contains recognition pattern of the DR/MyWebSearch S818152”

Is this a real virus alert or just a false alarm?

thanks anyone!
