Windows Service Pack 2
 

What a piece of crap. I've uninstalled it and now my computer is running so much quicker. For your firewall needs, just install ZoneAlarm. It's free and very effective.

I had a lot of trouble with this too. It made it so my computer wouldn't load windows for a couple of days. One of my friends ended up uninstalling and reinstalling Windows for me. I mean, I'm not great with computers, but I can't think of anything else that would have made it do that.

We did a lot of testing with it before we deployed it on all the workstations at work and didn't end up with any problems, although we did disable the firewall since we are already behind 3 corporate firewalls. If you already had a firewall installed, they can conflict and cause a lot of problems. Since installing that, with the Google pop up blocker on all of our machines at work, I haven't had to spend any time cleaning adware or spyware off of any PCs and I used to spend about 4 hours a week cleaning people's machines. I run it at home with the firewall on and it's doing fine, but I don't have a lot installed on my PC at home.

I have SP2 on my computer but I don't use the firewall. I have McAfee instead. I've heard that many people are having trouble with Microsoft's firewall. There's a lot of bugs in it still.
