    This is something that really worries me, I've heard it to.
    Also I am getting conflicting results when scanning for the patch
    installation. I've been using MBSA, GFI LANguard and Retina which all
    tell me something different.
    Which one should I trust??
    Or is there something else I should be using?
    
    Thanks
    Mike

    I have seen, and have heard other reports of, msblaster.exe worm
    infecting a Windows computer that had the proper KB patch specified by
    the 03-026 advisory.  In the instance I personally saw it was a Windows
    XP Professional workstation that was completely patched.  The person who
    used the workstation was surprised that they were infected since they
    has applied the patch and I verified (via Add/Remove Programs) that they
    did, indeed have the proper patch applied.  I checked with my parent
    organization and they had been receiving sporadic reports of patched
    machines being infected despite being patched.  Unfortunately I removed
    the worm from the computer without copying it so I don't have a backup
    of it for analysis.
    
    
    
    Has anyone else been seeing this phenomenon or do they have any idea why
    this might have or might be happening? I know for a fact the patch that
    was used came straight from Microsoft so I don't suspect a faulty patch.
