  Using Wilsonian procedure (renormalization group improvement) we discuss the
finite quantum corrections to black hole entropy in renormalizable theories. In
this way, the Wilsonian black hole entropy is found for GUTs (of asymptotically
free form, in particularly) and for the effective theory of conformal factor
aiming to describe quantum gravity in infrared region. The off-critical regime
(where the coupling constants are running) for effective theory of conformal
factor in quantum gravity (with or without torsion) is explicitly constructed.
The correspondent renormalization group equations for the effective couplings
are found using Schwinger-De Witt technique for the calculation of the
divergences of fourth order operator.
