For the past few months i have noticed that my Vista HP Pavilion dvd6565us has been running really slow. Typically to open an internet browser it takes a minute and then everything seems to happen in slow motion once it gets online. Also the fan always seems to be running and the bottom of the laptop gets really hot. Finally I have the free comcast version of Norton 365 and it is always telling me that I have high disk usage host process for windows services. Anyone know if there is something wrong with the computer. I have run Comodo Dragon, Norton Anti Virus and Malware bytes with nothing being detected. Also when I run a full scan on Comodo or Norton it can take over 24 hrs to run a full scan.
