Programs Opening... but not?

I am running Vista, everything should be running fine and such (Got
antivirus, adaware, spybot SD, etc.) and yet my computer is now not opening
programs. I click to execute, then nothing. When I open task manager, it
shows that it is running, albeit not and with a very low memory usage.

Which antivirus program?

Check task bar.
