Chrome Browser Redirect Question

I had a question that I wanted to see if anyone has encountered or heard of. At my work 2 devices had all search results in Google Chrome redirect. On the desktop all image search results would come up with large people. On a Chromebook any search result came back with porn. Unfortunately someone wiped out the desktop so I was unable to get my hands on it to look it over. The systems are generally locked down (the desktop by GPO) and the Chromebook by Google admin. Anyone run into this before? Also the workstations are Windows 7, 8, 8.1 Thanks
