Try Malwarebytes anti-malware (MBAM) and ADWCleaner.
also check the switches that may have been added to the shortcut links that you use to open Opera if it says anything other than this "Username\AppData\Local\Programs\Opera\launcher.exe then delete the extra until it just says that open opera and see what happens also +1 for the malwarebytes and or ADWcleaner
