I had malwarebytes and Spybot but I was unable to run or delete them. I deleted files and registry items manually and reinstalled and still they would not run. I have a previously cloned C drive on D drive and ran malwarebytes from there. It found four trojans and the Google problem solved together with the inability to update AVG. I believe the trojans had stopped all the malware programs working. I have now reinstalled them OK.
