Security Tool Virus......Cant run any antivirus software. HELP!!!

[kdaychoi]

My computer was infected yesterday with a fake antivirus program that installs a "Security Tool". It attempts to run its own antivirus software on my computer and get me to purchase their software. Obviously its a virus. However, when I try to run MalwareBytes AntiMalware, or my Avast Antivirus I cannot. Additionally, I can't add/remove programs on my computer.  I attempted to run ERUNT and other online scans and they were again unsuccesful. The only program that I have been able to open to scan for viruses has been Avast Antivirus, but my computer keeps randomly shutting down before the scan is finished. What should I do now? What can I do?

Thanks
