Your browser has been hijacked? Did you use a utility to scan for BHOs?
Did you try reinstalling your browser? Did you look at your Hosts file?
I have read several threads & postings from ppl with the same problem, tried most of them to no avail.
The Malware or Sptware on my XP System is just too elusive.
I have installed & run on a daily basis Malwarebytes. Also Super anti spyware pro and have uninstalled Virgin pc guard & installed AGV.
I'm still getting redirected to unwanted sites & cant get anywhere near the Microsoft site to update.
I am currently scanning system & going to create new & delete old restore points when it's done..
Failing that any more suggestions would be greatly welcomed..
