Mcafee Viruscan and Windows 95

We have a number of PC’s running Windows 95 and Mcafee Viruscan 4.51 SP1 that are having conflicts. At first machines would Blue Screen with and error in MCSCAN32.vxd when the user would open a word or excel document. Then found it also happens simply logging in and moving files. Updating MDAC and Jet engine helped but haven’t elimated the problem. Short of Disabling Viruscan haven’t found a solution and Network Associates haven’t came up with a solution either. Any ideas?
