Hello @ all,
I have exact the same problem. The first time in my life that avast lost (till now) against a malware… 
I have a Windows 7 64bit PC. And I want to clean the computer with avast, mbam.exe, spybot… Nothing helps… I want to try the spyware terminator or a antivirus boot cd this week.
Search in google:
avast malware csc.exe
And you find some threads from 2013 with the same problem. I hope you find a way to fix it? Please reply the way in this thread!!! 
Thank you so much and nice greetings from Germany,
Flesh
