rules for Avast datestamping into message header

[crub]

Dear all,
I wonder when does Avast add the datestamp into the header of the received messages.
Why ?
because I recently discovered in my Outlook 2010 a couple of old messages dated Jan 2013 (90 days before) received this month (Apr, 2013).
I suppose they have been sent on Jan, 2013 but...the date stamp of Avast is 09 Apr, 2013 !

I am not sure whether the header is modified by Avast
- when message is read
or
- when message is recepted
Could you please tell me ? Thanks in advance to the experts, Best regards, Crub.

The time/date stamps are made when posted.

edit: I have the time stamp set for my local time.

Unless you are using MS Outlook, I don't believe you can say what is happening as Outlook and avast are somewhat different.

Since there is an avast plug-in for MS Outlook, I don't know if like in the past there used to be an option for checking of archive email folders when opened. I don't know if that option still exists and if so when these emails are rescanned would the avast header scan details be changed.

Hello,
thanks for your reply,
right, when a message is posted with an Avast client, date stamp is set on current date.
But what's up with a no client Avast ?
The case now is I am receiving messages checked with Avast when they arrive in my Outlook..
So, do they are stamped while reception or while reading (displaying) ?
that is my question...
regards,
Crub

Hi DAvidR
While checking header of a received message in Outlook in mime format, you can display a first datestamp set by the sender.
another date located @ last line is set by Avast.
I wonder why these two date may differ with 90 days into th same message received !
So i presume the last line is set when opening or when receiving.
feel free to help anytime for this topic,

Unfortunately there is no way I can test as I don't use MS Outlook, I was working on the assumption of a feature in a previous version of avast and the Outlook plug-in.

If there was an option to scan MS Outlook archives when opened my assumption was that these emails in the archive (not just the archive as a whole) are scanned and f that mat inadvertently change the header information.
