When I do a search in google, my browser automatically switches to searching through Yahoo. This happened suddenly earlier tonight. I have tried switching my default browser to google, deleting yahoo as a browser, looking for extensions to be deleted, and done a reset and cleanup. None of these solutions resolved the problem. I think I have some type of malware but I have scanned with webroot 3 times with nothing found. I also tried changing my scan settings in Webroot: turning off and turning back on the “Detect Potentially Unwanted Applications” button and then scanning, but that did not help either.
