Another helpful step is to run Mbam from safe mode. Be careful with that particular virus, though. I ended up having to go into my registry and manually remove the processes even after my pc was clean. (I don't recommend that way. I've killed enough OSes to know only a fraction of what not to change/delete.) For future reference, I'd recommend DVD-RW and external hard-drive back-ups to attempt avoiding the process again.
My little bro's computer was once infected with a same kind of virus. That was rogue (fake antivirus), which would not allow any app to open, not even browser.
You can try out what @DoctorV23 said, you can give this software a try. But the problem with my bro's computer was, that rogue (fake anti virus/malware) didn't allow to open browser, so we couldn't download anything.
What I did then, I opened the "task manager" -> "Processes" and killed that process (fake anti virus) by right clicking and selecting "end process tree". It allowed me to open browser. But that malware opened again and again by itself, and I kept on ending it.
I downloaded malwarebytes anti malware from download dot com, and it successfully removed that malware and his computer was absolutely fine.
What Doctor said and remember USB drives are your friend. Remember to scan the drive clean before you put it into any other computer. Also keep in mind there are some offline antivirus programs out there (Microsoft makes one for free) that will boot off a USB drive or CD and scan a Windows system while the Windows image itself is not running.
Does your laptop have a recovery partition on the hard drive? If all else fails, access it to restore your laptop back to the day you first bought it. Be sure to back up any important files before doing this.
What the Doctor ordered... if your browser is not working, maybe you can use your phone to download the above programs; then transfer to your computer via USB (or SDCard reader if your phone has an SD card)?
1. Download and run rkill: [link] - it attempts to shut down malicious processes which interfere with scanning (there's a description on the page). 2. Directly after running rkill (don't restart the computer), update and run MawarebytesAntimalware (free version, quick scan): [link] and remove anything detected.
