repetitive scan/removal

emac g4

os 10.5x current

nav 11x current

clamxav 2x, current

 

on scan norton finds w89e85t5.exe at Library/w89e85t5.exe, which clamxav fails to pick up. I delete this each scan/detect, but the hit returns. this is a family computer, I'm not shure where everyone is going/doing. This may be a constant reinfect, but the vulmerability protection isn't stopping it.

is this possibly a false positive? if so, how do i test the hyopthisis?
