Outlook Express 5.0 Open to Security Breach -- Microsoft has issued an alert about a security hole in Outlook Express 5.0 for the Macintosh. Essentially, a malicious person could send a specially composed MHTML (MIME HTML) message to an Outlook Express 5.0 user. That message would then automatically download a file to the user's default Download folder without the user's knowledge. (You set the Download folder in the Internet control panel, Internet Config, Internet Explorer, or other Internet Config-savvy application.) If that file were a destructive application, and if you were to launch it, damage could occur. This situation is similar to receiving an application as an email attachment. In this case, though, you won't be able to connect a message to that file; at some point, you'll just find an unidentified application in your Download folder with no indication that it might be dangerous. Although Microsoft is working on a fix, the only solution at the moment is to open only downloaded files whose source you can identify. [ACE]
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
