A reader brought to my attention a thread in Microsoft’s discussion forums for Windows OneCare titled “Outlook and Outlook Express Mail Store Missing or Quarantined“. The thread started with a message in January and it’s still running today, with no clear resolution. In brief, if you get a virus in an email message received by Outlook, OneCare’s next virus sweep may quarantine or delete your entire email store. If you receive a virus via Outlook Express OneCare may quarantine or delete the entire folder containing the virus. Really!
The proposed solution is to exclude your email from the virus scan.
Now how did most virus infections get to your computer again?
