If you run OneCare 1.5 and have a malware email sent to your Outlook email client, there’s a large potential that the OneCare scheduled scanner will place your entire PST file under quarantine or other actions depending on what the administrator has set (which could include even deleting).

What’s really disturbing is that this problem existed in version 1.0 and was fixed and now in version 1.5, the issue crops up again, and with its exposure of its products, it smaked off lots of innocent user’s PST file.

There’s a patch expected to be released Tuesday (today 13th).

The issue could also affect other email clients including Outlook Express, so do exclude email extension for scheduled scans for now till M$ fixes their boo boo (Again!!!)
