I opened Chrome today to find that it was set to Yahoo, specifically this website: search.yahoo.com/?type=714647&fr=spigot-yhp-ch
And when I tried to search through my browser, it was set to search Yahoo also. I attempted to reset my homepage and my default search engine on Chrome settings, but even though the settings were saved, it still kept opening to Yahoo.
I found the culprit, SearchSettings.exe by Spigot Inc, and deleted it from the Control Panel. Unfortunately, that seems to have been a mistake, because my browser's preferences have still been overridden (on Chrome AND Firefox AND IE), and I keep being redirected to this Yahoo-Spigot homepage.
I scanned with Microsoft Security Essentials, it detected Exploit: Java/CVE 2012-1723 but gave this error message: "Security Essentials encountered the following error: Error code 0x80508023. The program could not find the malware and other potentially unwanted software on this computer."
I scanned with Malwarebytes. Did not find anything.
Attached the DDS files. Thanks for taking the time to do this, I really appreciate your help! dds.txt
