Step 1: Windows Disk Cleanup Utility ============

3   Click Advanced options and select Move infected file to Chest on the first dropdown list and leave the other one as it was. Click Schedule
4   You will be asked for a system restart. Click Yes to do it now or No to let avast wait for you to manually restart your PC
        NOTE: Optionally, you may enable scanning of archive files. If it is enabled, scanning would be more thorough but would take more time

Got the same problem with Win32:Malware-gen
Infected file is windows/system32/ctfmon.exe

I'm not sure it infected. Virus total show 5 warnings from 40 tests. File was tested by other antivirus programs, there are no any problems.
I see many people got the same notification from avast, but other files are infected.
Is  this new false alarm?
