Taking a break from my detailing to update this for the site admins: I'm an IT consultant and have been running into the exact same issue the other folks have been describing. Ran autogeekonline.net through some tools and found this:
Scan Results - Free Website Malware Scanner
"Malware entry: malware.forum_redirect.1
Description: Infection that targets mainly outdated vBulletin sites with the VBSEO plugin. It redirects visitors coming from search engines to one of the following sites: myfilestore[.]com, filestore72[.]info, file2store[.]info, url2short[.]info, filestore123[.]info, url123[.]info, dollarade[.]com"
Basically, there's a random redirect happening because of an outdated VBulletin SEO plugin that's infected with malware.
Hope that helps, I'll send you my bill.
