The replies did not help me very much sorry to say, can I please add more info in case it helps.
In safe mode I have done complete scan with AdaWare Spybot Ewido Regseeker M/S Malicous tool removal but I am still getting these adverts under web pages that I close including Webuser.
I have done a printscreen of a Hijack Log---M/S Tool result-- so these are available if asked by anyone to analize.
