Hello, I've searched these forums for how to fix an infection that causes Google and other search engines to redirect, but everything seems to be very situation-specific. If someone here could help me out, I'd appreciate it. I'm using Windows XP. As I said, search engines are redirecting links to various advertising sites. It seems to be at random. I'm also unable to get to the Microsoft Update page -- it says the site can't be found, or something like that. Microsoft.com is fine, though. I WAS unable to update Malwarebytes, but I installed the newest version from a thumb drive, ran a scan, and it caught whatever caused that problem. Now mbam is able to update itself. The latest scan turned up nothing, but I'm still having the redirect problem. Any help would be great. Thank you all so much.
