How to Remove/Uninstall Yontoo Virus (Yontoo Ad and Yontoo Toolbar)?

Is yontoo supposed to be in my add-ons? 

Yontoo attaches its ads and toolbar on your browser, so usually it should be in extension/ plug-in/ add-on. But no progress is made from there because one simply cannot find its trace. Getting into Control Panel and removing yontoo there helps nothing, both yontoo ads and its toolbar survive even there’s no its indication in Control Panel and browser. What happens? Is that a ghost? Why would an add-on be that difficult to get rid of?

How would a tiny one be capable of bringing junks and virus into your system in the coming days?

The answer lies on the backdoor it makes. A light one doesn’t mean it is an innocuous one to your system. Yontoo virus manages to open up a backdoor invisible to you by inserting its critical part (registry entries) into the kernel part of the compromised machine. Once the backdoor is in shape, you will get all its affiliate things, that’s why PC users who get yontoo ads would finally get yontoo toolbar and vice versa. A backdoor can also be exploited by random virus. Therefore, we suggest a quick remove of yontoo virus, no matter you have its script pop up or toolbar.
