I have encountered a malware that used the MWT file extension used by the Metastock stock analysis program for day traders. MWT files are templates, and MS Word may be able to open them (not sure--I don't use Word). So if you are a Metastock user and have custom file extensions for ClamWin to scan, you might want to include the MWT extension in your custom extensions. If you are a Clam Sentinel user, make sure the MWT extension is included in your extensions to scan. This is the first time I have encountered this, so it is not very common (yet?).

Regards,
