A week ago the internet for this laptop started to slow down--streams stopped to buffer way more frequently and even some web pages took way to long to load. Yesterday it got worse. My mouse cursor always has an hourglass next to it, and the internet is even slower, it takes 30 seconds to load my gmail. Worst of all, my administrator password isn't working anymore(I'm on the guest account right now). Can a virus change the admin password on your computer? I can't even run an Avira scan because it asks for admin. The computer I'm on is using Windows 8.1. Any help would be appreciated.
