Computer virus problem!?

i installed panda antivirus into my laptop. but it doesn't seem to get rid of all my virus problems. it's so irritating that my computer keeps telling me that i have spyware. i tried so may programs like NORTON ANTIVIRUS and PANDA INTERNET SECURITY, but they are still there. i also get a notice that says:

ADWARE HAS BEEN DETECTED. ACCESS TO THE FILE HAS BEEN BLOCKED, BUT IT COULD NOT BE ELIMINATED. CHECK THAT THE FILE IS NOT ON A WRITE-PROTECTED DISK OR IN A COMPRESSED FILE.

what does that even mean? and does anyone know of any really awesome programs that detect everything and clean out your computer completely?
