Threat? Not Threat?

SpencePorter

Hi!

Earlier this evening, I got a notification that a threat called Exp/MS04-028 had been detected on my system.  I went to Quarantine, where I found it listed with a statement that the threat needed to be manually cleaned.  I then went onto the Sophos website for information about how to do this.  When I then returned to Quarantine, with the intention of trying to remove the threat, the threat was no longer listed--Quarantine was empty!

What does this mean?  Is my system infected or not?  Do I need to do anything?

Thanks!

Spence

    This is an interesting one...

    Exp/ refers to exploits as opposed to actual malicious software.  This exploit is http://technet.microsoft.com/en-us/security/bulletin/ms04-028

    It looks like what happened is your web browser partially downloaded and cached a JPEG image, such that the references in the beginning of the image file were pointing to memory space outside of the file's size (as it was incomplete).  When the image finished downloading, this condition went away, and so the threat did as well -- meaning that the quarantine was lifted for the file.

    Does this make sense?
