Trend Micro AV product was exploitable last week, from coordinated public
disclosure of a vulnerability on Oct 19, not patched until Oct 25: they were
notified Sep 9, and confirmed the issue Sep 25. Update immediately!
he Trend Micro AV product does not seem to perform as well, or rate as highly,
as the default, free MS Windows Defender, and other better AV packages.
Some of their vulnerabilities seem head-slappingly obviously *BAD*, like the
latest, allowing any malware called cmd.exe or regedit.exe to be downloaded from
anywhere and run without any checks!
Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
