Computer runs even slower now

Why is it that my computer runs even slower after I installed AVG Protection as well as AVG Maintenace? Its very frustrating? I scanned and removed all the files etc that AVG recomended to get better performance, but I swear nothing is any better? Its worse!  This goes for for on and offline. Can anyone help?
