Troubles with slowness.

Hello, first of all i am not sure if my problem is a virus or some thing as i have run several scans with Norton and even used the Norton power eraser and still i have this problem. When i open the internet explorer it takes absoluetly forever to display google to search for any thing, then once it does and i search for whatever, it takes just as long to open. Some times it wont open at all and just keeps the screen blank with the tab saying what its trying to open.
I have tried many things to get it running normal speed again but nothing is working and i am in need of some help. So if any one could help me out i would be very greatful :)
Oh and this problem has only started at the begining of the week and is just getting worse and worse.
Thanks, Sarah.

scrooge

Nope i haven't tried to reset internet explorer, i'll have a look in to doing that, all tho i have no idea how to reset it. :/

Ok i have done it, and it is a little faster i think, still it is running much slower than it was last week
Thanks for the tip on reseting the internet explore tho :)

Yeah I have deleted the history and it is still runs slow I even tried using firefox and it's slow i open google search but I can't open any thing else cause it crashes.

Have you tried cleaning your pc for malwares and viruse? From my experiences programs such as Ccleaner, Superantispyware, and Malwarebytes Antimalware. I use them once a week to make sure my pc is not infected and also gets a better speed connection. Though I am still getting a slower browsing with IE9, but have no problem with other browsers.
