Microsoft's AntiSpyware

Microsoft’s Antispyware really sucks, it was troubling me for the past 2 weeks and I finally managed to uninstall it.I don’t have any problems with Microsoft, I generally like their products and have nothing against them.But this Antispyware was literally spying on my computer.

First some of my programs won’t work just because of the fact Microsoft’s AntiSpyware was blocking them.
Secondly anything I install even a small program, it requires a permission.Antispyware takes too much time to load on Startup.
Lastly, when you try to shut it, you just can’t, for a moment it goes but after that you see it again in the sidebar.After all this I thought of getting rid of it and uninstalled it.As you all know it is still in the Beta stage, could be because of that – what say ???

As far as my rating goes after using it for almost an year I give it 5.5/10.
But, I have learnt one thing from this experience, that you should not install any program in the beta stage especially on your PC.
Any suggestions on which AntiSpyware should I use, or not use at all.Anyways if you have any opinion comment, even if you don’t feel free to comment.
