SUMMARY
=======

McAfee SCAN versions 99 and 100 may incorrectly report the Israeli Boot [iboot]
virus is active in memory if MS-DOS VSAFE is running.

This situation occurs when McAfee SCAN finds nonencrypted virus signatures in the
VSAFE memory segment used to store the virus signatures.

McAfee is researching this problem.

The SCAN product included here is manufactured by a vendor independent of
Microsoft; we make no warranty, implied or otherwise, regarding this product's
performance or reliability.
