  An Artin algebra is by definition virtually Gorenstein if the class of
modules which are right orthogonal (with respect to Ext^*(-,-)) to all
Gorenstein projective modules coincides with the class of modules which are
left orthogonal to all Gorenstein injective modules. We provide a new
characterization in terms of finitely generated modules. In addition, an
example of an algebra is presented which is not virtually Gorenstein.
