I have searched the internet, Chrome help, and McAfee help for a solution and haven't found anything yet.
Regardless of the browser I use (IE or Chrome), when a new tab is opened it goes to a Yahoo search page. It also redirects to Yahoo after I submit a search and during launch, when I have it set to open to other pages. I have removed Yahoo as a search engine in Chrome and designated Google as the default.
When I first noticed it, I ran a McAfee Security Center FULL scan, and it came up empty. I uninstalled/reinstalled Chrome as well, but it isn't just happening in Chrome and didn't fix the problem. I also removed the McAfee Web Protection since I read that it uses Yahoo. I found that something called Results Hub was installed on the computer, so I removed it. Once that was complete I could also automatically see all hidden files. I did some more research on the McAfee forums and found so I tried the RootkitRemover, Stinger, and Malwarebytes Anti-Malware. Malwarebytes actually found 54 bad/suspected bad files and removed them, but the original issue remains.
Thanks in advance...
You're probably seeing the result of accepting a popup from McAfee to allow "Secure Search", a feature of SiteAdvisor/WebAdvisor, a browser security add-on from McAfee. Opem IE and click the tools icon at upper far right - it looks like a cogwheel.and you could have then opened WebAdvisor settings and turned off Secure Search and set it to monitor in all browser search engines, that would have stopped it and would also offer some web security as it appears you could be susceptible to malware.
I wouldn't remove any security measures if I were you. You can reinstall it from here: McAfee SiteAdvisor Software – Website Safety Ratings and Secure Search
From that link you have posted (which I published by the way) also scan with AdwareCleaner and another scan using MalwareBytes Free (as per this removal guide: Removal instructions for Results Hub - Malware Removal Guides and Self Help Guides - Malwarebytes Fo... )
If, after all that it still persists, scroll down that link to the Hijackthis section and follow the advice there for expert guidance from a specialist malware removal forum.
