IE7 is Microsoft's latest web browser. It is a clear rip off of Mozilla Firefox
. Since its release there has so far been three security flaws, as opposed to 0 from Firefox 2.0.
IE7 is forced upon you by Microsoft'a Automatic Updates, although you can revert to the more flawed IE6 at a later date.
If IE7 is your only web browser head over to www.getfirefox.com to download Firefox 2 and re-discover the web.
