According to google my website is block and it contains malware. I called my hosting provider and they said my site does not have a virus. They told me to register it with google. I verified the site and apparently malware code has been injected into the site's code. This means someone managed to hack it. If you log into the google it shows two instances it identifies. I have tried to go through and find them but this is way out of my league. What do I do?
