On Tuesday,8,2014 i was looking up ways to speed up my windows XP computer it helped but it was not enough i tried different things like adjusting settings, disk clean-up and doing a defrag it did some help but it was not enough i tried scanning with my antivirus software but it only found one thing i removed it but something was still missing so i downloaded malwarebytes and that thing found nearly 300 bad things and i removed them and when i rebooted my computer it was working fast and smooth like it did before. Mortal lesson: if your computer is slow it may have viruses or other junk on the computer use malwarebytes and spybot search and destroy they will scan your computer find viruses and speed up your computer and make it work like new again
