I've done over a dozen scans with malwarebytes & adwcleaner, reset my google chrome settings, deleted all my chrome extensions, uninstalled all recently installed programs, but i cannot get rid of this virus. When i search something on google i will often get redirected to extension.citypage.today & then Bing search. I have windows 7 professional 64 bit OS. One site told me to download SpyHunter to get clean my PC but it won't open. What should i do?
