Try these:
1. Delete temp Internet files. If you haven't done that for months, it's very likely your problem.
Tools > Internet Options > [General tab] Delete Files.
Reboot afterwards for luck :)
2. Go to Windows Update on the Microsoft site.
Should be in your Start menu. Download and install any critical updates first, if you're still in trouble, go back and download the rest of the updates.
Which version of Windows are you using?
