Error message in Forefront Security or in Antigen 9.0: "ERROR: Call to engine scan function returned virus found with no virus name"
SYMPTOMS
On a computer that has
Microsoft Forefront Security or Microsoft Antigen 9.0 installed, one of the following error messages is logged in
the Forefront Security program log file or in the Antigen program log file:
ERROR: Call to
engine scan function returned virus found with no virus name within Internet
scan job
ERROR: Call to engine scan
function returned virus found with no virus name within Transport scan
job
This problem occurs only if the version of the Microsoft Anti-Malware scan engine
is 0.1.10.47.
RESOLUTION
To resolve this problem, update the Microsoft Anti-Malware
scan engine.
Note A new scan engine was released on June 21, 2007. The Microsoft
Anti-Malware team changed the engine so that the engine clears the registers that
are used during the floating-point calculations before the engine returns
control to the Antigen mapper.
STATUS
Microsoft
has confirmed that this is a problem in the Microsoft products that are listed
in the "Applies to" section.
MORE INFORMATION
If you use Forefront Security or Antigen 9.0 together with the Microsoft
Anti-Malware scan engine to scan files, you may experience false-positive results
for uninfected files. Some .pdf, .pptx, .xls, and .xml files will be tagged as
infected files. These files will then be removed even though no virus is present.
The version of the Microsoft Anti-Malware engine that triggered the
defect in Antigen was deployed through a rapid update on June 15, 2007.
APPLIES TO
- Microsoft Forefront Security for Exchange Server
- Microsoft Forefront Security for SharePoint
- Microsoft Antigen for Exchange
- Microsoft Antigen for SMTP Gateways
