Computer Hangs at Shutdown If Anti-Virus Software Is Installed

The information in this article applies to:


 * Microsoft Windows 95

SYMPTOMS
With both anti-virus software and a PCMCIA (PC Card) adapter installed, your Windows 95-based computer may stop responding (hang) with a "Windows Protection Error" error message during the shutdown process.

CAUSE
The Pccard.vxd driver can cause memory corruption during shutdown while it is processing a CONFIG_REMOVE message for an adapter. This may cause anti-virus software to hang with a "Windows Protection Error" error message.
