Even though your computer should receive automatically, the latest in what has become a pretty typical day of downloads from Microsoft, I seriously suggest changing your browser habits and that starts by using a different web browser.
I have talked about this before, but now, even more so does it appear evident that the long awaited for Internet Explorer 7.0 is going to arrive a little too late. This latest article from zdnet explains.
If you haven't already visited my SOFTWARE/SUPPORT page, I suggest doing so. While you are there you can install the latest AVANT BROWSER which is full of great features not yet available through the Internet Explorer. One great feature is the fact that you are pretty safe, since one of the features with the Avant Browser is the ability to check for updates whenever you open the browser, and by clicking "ok" when there is a new version available will ensure you have the latest in security built right in. Unlike the Internet Explorer which depends heavily on the rest of the windows 'updates' to be completely safe and secure.
