My husbands computer runs Microsoft Security Essentials. The icon is red and says it needs to be updated. When I try to update, it says it is not installed. when I type in microsoft.com, it takes me to google search. When I search for microsoft, and click on a link, google said the page is missing. If I click on the "help" button in MSE, it takes me to the page where I can download MSE. I believe this is a fake page and a fake download button. ANY anti-virus software website I try to type in the address bar takes me to google search. I've tried using google chrome as well, and the same thing happens. I have tried Safe Mode, and the same thing happens. I am at a loss as to what to do. I need to scan his computer, but can't figure out how. He is running Windows XP, SP3 I believe. I get the same "google can't find the page, we don't know what happened" when I try to update his Malwarebytes and Super Anti Spyware.
