Spool 32 on Network Printers

We recently upgraded McAfee Virus Scan via Zenworks and it has caused continuous Spool 32 errors to appear when printing from HP network printers. It sometimes prints but locks up afterward and forces the user to cold boot. If it does allow them back into the system it removes all their printers and they still must shutdown and reboot to recognize the network printers again. I have tried many of the suggested fixes in Novell and Microsoft but no success. On some PC’s I have had to completely remove McAfee before the PC will operate properly. Help please.
