Is the game 'Zwinky' virus?

is zwinky a virus? i've had it for two years now. nothing happened. i've read other questions but the answers from experianced people didn't seem to be the same thing that happened to my cmp. nothing happened. it didn't install a toolbar. i just want to know is it really really a virus? i have about 6 virus programs, so i think i can search and destroy the virus it caused. im confused now. please help?
