what is this IOfficeAntivirus Module (MpOAV.dll)

[Guest]

Looking around the Window Defender Folder and notice this IOfficeAntivirus
Module (MpOAV.dll).

There is a feature in Windows that allows applications to use a programmatic
interface called 'IOfficeAntivirus' to scan a file before opening it.

For example, your email program may initiate a scan of files sent as
attachments before launching them, to try and ensure they are safe.

Antivirus (and antispyware) scanners can register to be called via this
interface - the DLL in question is used by Windows Defender to support this
mechanism.

The interface has been around for a while, and the name is a bit misleading
these days.

Some additional information on the API is at:

So then, Mike...can you tell me if, as is my case, I have Norton Antivirus
checking my email both incoming and outgoing...and everything is working in
that respect in just a peach fashion...

If I install Beta 2 Defender, will it's email antivirus service bump out my
Norton one? I would like to have the option to use the email virus scanner
of my choice.

Thanks
Paul D.

No, Windows Defender should not interfere with the email scanning of your
existing antivirus program in any way.

Thanks, Mike! Though I would feel better if the word "should" in your
response was "will", but working as I do in the software world, I understand
the inherent difficulty of making such a word switch
