My first step would be to clear all caches, (IE and Chrome). Download CCleaner, install and run it. Use nothing but Stock settings, (in other words, do not alter the settings on the first page). Before you click Analyze or jump in to Run Cleaner I would first visit the Options page, then Cookies, and save any cookies you don't want deleted.
No need to use CCleaner's Registry scanner option.
Tell us more about this system, make and model, how old is it, and any other problems, eg opening applications, files, documents, videos, etc? What changed when you started experiencing this?
Also, about SAS. Is it running in the background? If so, disable that and just use SAS as a stand-alone manual scanner. Do you use any other security scanners like Spybot Search & Destroy, or Lavasoft's Adaware? If so, try uninstalling those. They don't sit well with today's anti-virus scanners.
Tell us about Norton. Which suite? Is it's license still current or is waiting for you to renew that?
My Laptop has been slowing up in the past few days. Now it
will not load some pages or takes an age to load others. I
checked LAN settings but everything that should be checked was.
I have run Super Anti Spyware and Norton but everything is OK.
