Keyword(s): kberrmsg win95

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.
