Avast can't delete or move to chest: Win32:Beagle-CA [Wrm]

I just upgraded to Avast Pro, and did a full scan. It came up w/ two virus files. I 1st tried moving them to the chest, then just deleting them, but got an error report saying operation could not be performed. Any ideas on how to get rid of these files? The files are:

File name:
C:\Documents and Settings\Jonathan Craig\Local Settings\Application Data\Microsoft\Outlook\Outlook.pst\Personal Folders\Top of Personal Folders\Inbox\Unknown\2.zm9\06_05_2005.exe

Malware name: Win32:Beagle-CA [Wrm]

Malware type: Virus/Worm

VPS version: 091202-0, 12/02/2009

It is dangerous trying to remove infected emails in .pst files as it could result in the loss of all emails in that .pst file. So it looks like you have two infected emails in the .pst file.

Try finding the infected emails within MS Outlook, I don’t use Outlook, try searching for emails with attachments or navigating the path to the infected email with the attachment. Once found, don’t open the email with the attachment, delete it/them and go to the deleted emails folder and empty that too. Then if you have a function to clean-up/compact email folders that should effectively ensure it is gone.
