|@radovanov, isn't MBAM the same as MalwareBytes Anti-Malware?!|
For me Defender, MBAM, Spybot S&D and Avast couldn't get rid of this annoying google search result page hijack.
According to some the Combofix should be able to do something, but it is momentarily offline due to some serious de-bugging.
Don't know what to do anymore, hope someone comes with a good solution.
