Hello

Pretty new to all of this ...downloaded the ccleaner like two weeks ago, finally used it and since then I can only open one window at a time and every other page keeps freezing on me plus unable to use some java sites....anyone know whats wrong or how I can fix this problem?

Is your problem like this?
