Default Tab by Search Results, LLC
IE 10 on Win 8 on a desktop began acting strangely last month. Eventually IE 10 hard locked everytime it opened. I found and removed "Default Tab" by Search Results, LLC using the normal Uninstall Program. After rebooting IE 10 worked again. As far as anyone remembers the add-on was not intentionally downloaded and installed. It apparently redirects the search to Yahoo, but also appears to do so through their website. F-Secure and MalWarebytes did NOT flag it as malware. It may be a legitimate program but it also apparently caused the serious problems with IE 10 that got worse over time. I don't know how to submit this to F-Secure.
