Laptop behaving funny..

Hi I have a dell vostro laptop - worked fine up until around a month ago. Suddenly, occasionly there is now ridiculously high cpu usage. Im not sure if this coincides with the high cpu usage, but from time to time the laptop will start behing seriously slow - being reall jerky. Not sure what this is - malware, virus? Help please! Thanks in advance..
