It's working fine here with engine 4.3.20:
# uvscan --version
Virus Scan for Linux v4.32.0
Copyright (c) 1992-2003 Networks Associates Technology Inc. All rights
(408) 988-3832 LICENSED COPY - Nov 27 2003
Scan engine v4.3.20 for Linux.
Virus data file v4367 created Jun 16 2004
Scanning for 92006 viruses, trojans and variants.
We've had reports yesterday of a couple Windows servers that ran an old
version of McAfee that stopped working with the new DAT file. Upgrading
the McAfee software solved the problem.
