Before you go, I should mention that the AVG-AntiSpyware is just a 30-day trial, after which it will no longer give you real-time protection against spyware. You may wish to uninstall it now, or you can make use of it until the trial is up and install Spybot S&D as mentioned above and keep AVG as an extra on-demand scanner. It is your choice.
To speed up your startup a little we can remove a few unnecessary items.
Click on Start then Run and type msconfig. In the window that opens, click on the Startup tab then uncheck these items.

Click Apply then reboot. The System Configuration Window will appear at startup. Click OK.
Of course, what you want starting up is entirely personal choice. Your firewall, anti-virus and anti-spy are necessary.
