My Laptop Is At Risk!

Arghhhh... What's wrong with my cute laptop??? Windows Update turned into red with a white cross mark there, and being inactive since my computer is at risk! I tried to turn it on, but it couldn't work!

Well, I took the iniative to install Spybot, a well-known spyware. This is my first experience using such software, since I used to rely on trial edition of Norton, and recently AVG. But, I felt now it's never enough using such security suite. So, I used AVG for anti-virus, Spybot for spyware, and... firewall, I don't know what should I use (any suggestion???).

But then, I realized that Windows Security has also provided such features. Ahhh... Would it be conflicting each others??? Oh yes, another option is to install Kaspersky, another powerful security suite instead of AVG.

Anybody, please tell me what is the best for me to do? Since the notifications if my computer is at risk keep coming up, even I've used those security packages.
