A new malicious campaign is using a legitimate but old and vulnerable Avast Anti-Rootkit driver to evade detection and take control of the target system by disabling security components.

The malware that drops the driver is a variant of an AV Killer of no particular family. It comes with a hardcoded list of 142 names for security processes from various vendors.
