Virus found Win32/cryptor

Hi

I was busy on my laptop when suddenly i got a message from AVG free saying 2 new threats found.
I tried to delete these threats but it wouldnt let me and my whole laptop froze up.
i cannt remember the other virus that was found but the first one was.
Win32/cryptor fiocaxp.exe
and i constantly get a message that pops up saying "microsoft windows search protocol host stopped working and was closed"



*****Update****** just got another message pop up "consent for UI for administrative applications stopped working and was closed"

*****Update 2******

I get another message when opening most programs now saying "application cannot be executed.This file consent.exe is infected. do you want to activate your antivirus software now? with the option "yes" or "no" and if i press yes it takes me to some random Antivirus live website.
and also brings up one with the Searchprotocol.exe is infected.and explorer.exe
