Once downloaded, close ALL active programs, including your web browser. Then Install and update Malwarebytes (I'll assume that you have no trouble doing this)
Now run a scan with Malwarebytes ("Perform a quick scan" option should be sufficient).
Once the scan is finished, click on the "Show Results" button and it will present you the result. Choose "remove selected" to remove most traces of malwares on your computer.
Now, let's check whether the problem is solved. Close Malwarebytes and reboot your computer.
Install it. Then right click on it and choose "Run as Administrator"
Choose "Do a system scan and save a log file"
It should takes less than 30 seconds for Hijackthis to finish the scan. Post the log file on here or send it to my email. From there we can remove what Malwarebytes missed, for examples: registry entries and leftover files.

Do you have an antivirus program installed on your computer? If you do NOT, then it's probably a good idea to get one to reduce the chances of this from happening again. If you don't have the money, there are a few free antivirus programs that you can use:
Comparing to Avast, Avira has higher detection rate, but its free version pops up advertisement whenever it updates; and occasionally (once or twice every three months or so), it fails to update its definition.
Avast has adequate detection rate and has NO advertisement whatsoever as of now. You can install and choose more skins for it, too.
AVG . . . I've never used AVG before so I have no comment on it. My school has it though, and I find that it has really nice GUI, but I am not sure about its performance--at least not from personal experience. [ ThirdQED's advice column | Ask ThirdQED A Question ]
