When i do a search on google or Bing instead of getting on to the website clicked i am gettng rerouted to a different website advertising a product or clinic etc.. For example, when clicking on the mayo clinic site after doing a google search, i will get on to a site advertising a pain clinic. This is happening to me 80% of the time when i do any searches and it is **bleep** frustrating. I noticed this happening about 3 weeks ago or so.I ran the norton power eraser tool which said there were no risks? How can i correct this problem?
