My Avast AV is showing that Comodo firewall process is infected with virus

My Avast AV is showing that cmdagent.exe process is infected with Win32:FakeVimes-B [Trj]. I only have Comodo free firewall not antivirus. How can I disinfect it.

This is a false positive. Please report it to them via the method suggested in this article.

You made the memory scan? Right?

Dont get fooled by an antivirus program. Especially if it tells you that a competitor seems to be a fake antivirus.
