I searched with google and could find no specific virus to blame. What might work in WindowsXP is to download a fresh (uncorrupted) version of this msoeres.dll from http://www.dlldump.com/download-dll-files.php/dllfiles/M/msoeres.dll/download.html and insert it in the two places where it's supposed to be----->
C:\WINDOWS\system32\dllcache
and
C:\Program Files\Outlook Express
Why not kill off all viruses in your system? Then repair Outlook Express via windows repair on your XP disc and re-installing service packs SP2 or SP1 with updates. If you have broadband you can download these service packs all at once. Download is about 130mb.SP2 is more.
In XP repair looks pretty easy and you will be updating it at the same time. As a general rule, make sure OE is updated to the max with available patches
