Need help on DNS Unlocker adware problem

Hello! A couple of days ago I’ve downloaded some new soft, and with them, DNS Unlocker sneaked on my PC. I immediately removed the virus by using this article: http://pcfixhelp.net/ads/1649-how-to-remove-dns-unlocker, but today it appeared again. Probably, I incorrectly executed instructions, that were in the article, or I am just stupid, creating problems for myself, using untrusted sites = (Please tell me what can I do to clean my computer from DNS Unlocker. Except that, can somebody tell me, are the disposal methods described in this article useful or not? Maybe I just have followed the wrong directions =) I am waiting for your answers, please help me while my PC is still alive =)

Those are generic instructions which will not target all of the specific files

Please download Farbar Recovery Scan Tool and save it to your Desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

[*]Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
[*]Select additions at the bottom
[*]Press Scan button.

[*]It will produce a log called FRST.txt in the same directory the tool is run from.
[*]Please attach both logs generated.

Thanks a lot, but I’ve just loaded a backup from a month ago. Lost the Witcher 3 and Dragon Age Inquisition, but I will download them again! =)
