Much better if U start your own thread if U have an issue with this vulnerability.

After a scan has PSI shown U have a vulnerability? If so post the path(s) to the programmes it has found.

U have not really set up PSI correctly. By default PSI scans all hard drives whether internal or connected by USB cable.

Provided these drives are used solely for back up or are recovery drives or the i386 folder they can be safely ignored.

CREATING A GLOBAL IGNORE RULE
=============================


1.Click on the SETTINGS tab>scroll to the bottom & click on CREATE IGNORE RULE

2.In the RULE NAME BOX insert the Drive detail - My Backup Drive for example.

3.In the RULE BOX type D:\ (or the drive letter U wish to ignore). If it is the i386 folder use this - C:\windows\i386

4.Click SAVE IGNORE RULE>CLOSE

5.Carry out a full PSI rescan & all should be in order.

All hard drives will continue to be scanned by default but the result from the drives ignored will not be published.

The current version of MSXML 4.0 is version 4.20.9876.0 This is the version for Windows XP SP2 all the way through Windows 7. The actual download page from Microsoft for this version is http://www.microsoft.com/downloads/en/details.aspx...

It is KB973688. I found the link by Google: MSMXL 4.0 version 4.20.987620
Don't ask how I found this to be the most current, other than it was on some Secunia PSI post which I can no longer find. Was about to install KB954430 which was version 4.20.9870.0 which would have been fine for my XP SP2 PC, but then realized it would not help those of you with Windows 7.

Although the version U have is secure it is not the latest version. MS have moved on to SP3 which is the final SP. Support for SP2 ended on 13/4/2010.
