As of late I've noticed my laptop running extremely slow. It doesn't matter if I'm surfing the web using Google Chrome or just simply using regular programs. I tend to clear my cache, do a disc cleanup, clean my registry and spyware on a daily basis. I defragment my laptop at least once a month and I run an avast scan every couple of days or so. I haven't seen any traces of a virus on it, so what would you recommend I do?
