Norton's Antivirus

[Eminenz CW]

I bought a Norton utilities upgrade online on the Norton website. I downloaded the file and ran a virus scan on it with 2 online multi virus scan engines. Both multi scan engines picked up Trojans. Phoned Norton about this and they assured me it was safe, and that I probably got a false positive reading. I am still afraid to run the file and would like to know if there is a way I can be absolutely sure that it does not contain a virus?

I do not like this antivirus. I like Avast.
