NOD32 question

Does anyone know how to get NOD32 to allow Side Step - it's a travel search engine/software that integrates with IE. NOD32 insists it's dangerous, and flashes a warning everytime I open IE. I tried excluding it via the AMON setup, to no avail.

SideStep is also detectable in Spybot SD under PUPS.sbi, whatever "PUPS" is I don't know since searching for it didn't product any explainations.
