    Outlook and AV programs (All)

    I've got a multiboot system, with a different version of Office in each OS.

    OS on C has Office 97
    OS on F has Office 2000
    OS on G has Office XP
    OS on J has Office 2003.

    Main OS is on J and has NAV 2006.

    This week, I installed Kaspersky AV 6 in the OS on the G drive.
    While running a full system scan with KAV, I noticed that each of the 4
    outlook.pst files changed in size.

    outlook.pst on C changed from 353KB to 384KB.
    outlook.pst on F changed from 513KB to 560KB.
    outlook.pst on G changed from 480KB to 512KB.
    outlook.pst on C changed from 761KB to XXXKB, not yet finished..

    Sue Mosher's tyo2kp.pst changed from 624KB to 640KB.
    "Building Microsoft Outlook 2002 Applications.pst" changed from 7696KB to
    7744KB.

    Is it really necessary for an AV program to change the size of a PST when
    scanning?
    KAV did not change the PST file sizes when KAV was installed. Tools |
    Options, in Outlook 2002, does get a Kaspersky AV tab.

    Of course, since KAV is installed in the OS on the G drive, Outlook 2002 is
    the current Outlook.
    Does this mean that the outlook.pst installed on C and F have to get changed
    when looked at with the Outlook on G?
    Even if so, why would the outlook.pst on G change size as it is native to
    the Outlook on G?
    Scan has not yet gotten to the J drive, so I am wondering what is going to
    happen when KAV tries to use Outlook 2002 to examine an Outlook 2003 PST
    file.

    Next time I run a scan using NAV 2006 on the J drive, I'll try to remember
    to check whether NAV also causes the PST file sizes to change.

    Yes, there are bigger problems in the world, but my feeling is that I may
    need to restore each PST to its pre-scan condition.

    I haven't seen this before. Does Kaspersky add any validation checksums to files? Is there a possibility it did something to each attachment in your PSTs?

    An AV program better not modify ANY file.

    All it should be doing is examining scripts and attacments.

    In my case, as I do not Outlook, other than for VB/VBA testing, there
    is nothing in them there files.

    I do have a small vbaproject.otm.

    As I do not use Outlook, I have not looked at this before.
    Maybe NAV 2006 does the same thing?
    I'll try that after the KAV scan is completed.
    NAV usually scans about 1.2 million files.
    KAV is aleady close to 1.8 million files with a ways to go.
    KAV reports things that NAV ignores.

    According to info at the Kaspersky web site, NAV looks into .zip files, but KAV also looks into arjm cabm rar and lma files.
    By itself, looking into cab files would greatly increase file count.

    I expect that it's going to take about 30 hours to complete the scan. Thus far, a bit under 23 hours.

    file.<hr>

    As I expected, KAV did not change outlook.pst on the J drive.
    Since KAV is running in the OS on the G drive which has Outlook 2002, I expect that KAV could not open the outlook.pst on the J drive which was created by outlook 2003.

    Should this have resulted in an error being logged in the report or elsewhere?
    I'll check when the scan is finished.
