Websites wont display and mouse pad not working correctly

Hi.
I have a lenovo laptop running vista and recently the mouse pad began not responding all the time...literally running my finger over it and the arrow on screen doesnt move (this happens frequently), and also I am not able to view nearly half of websites (cannot connect to the internet), even though the connection is actually fine. I dont know if this i the right forum for this problem - but thought it may be due to spyware or something? Any help would be much appreciated! thank you.
