The first thing to do is empty your browser cache. Sometimes that's all it takes.
If the malware got past your antivirus and MalwareBytes, you probably need to have your drive scanned from an uninfected operating system. That could mean using a boot CD with an antivirus, like the Kaspersky Rescue Disk, or removing your hard drive and attaching it as a secondary drive to an uninfected computer that has an updated version of an antivirus already installed on it. Burning a Kaspersky Rescue Disc from an infected computer is probably not a good idea, but if you have a second computer maybe you could burn one from that.http://support.kaspersky.com/us/viruses/rescuedisk
If you've never burned an .iso file, or set your computer to boot from the CD drive instead of the hard drive in the BIOS Setup, you may want to just take it somewhere for a professional cleaning. Even if you manage to boot from the Kaspersky CD, you have to remember to download updates before running it or it won't find anything. YouTube has some videos on how to use it, if you want to search there.
Attaching your hard drive to an uninfected computer involves removing the hard drive and attaching it to another one, either by attaching it to a SATA cable connected to that computer or by putting it in a removable drive case. I'm not sure if you'd be comfortable doing that.
Once a virus infects, it may have the ability to control what your antivirus is able to do. So you can't trust your antivirus when that happens. Nor can you trust anything that is installed after the infection -- unless you know enough about what type of infection you have and what it is capable of doing.
You may want to consider reformatting and reinstalling Windows if you have a Windows CD. If your computer has a "rescue partition," it may or may not be infected.
I don't know what your particular malware would be called. But if someone else knows what it is, there may be other ways of getting rid of it. It may be relatively easy to remove once you know what it is and can look up removal instructions.
