it is a malware undetected by malwarebyte's antimalware, that stops dns to malvarebytes, any microsoft site, update etc, probably other antivirus sites. it is not in the hosts file, hosts file si correct and works, it can manually reinsert dns resolving e.g. to malwearebytes, but also newer data isn't effective in finding the malware by scan. no evident payload is detected, no slowing, no new process or service; but dns alteration is effective (and do not depends on any dns server), so virtually no possibility of upgrading any antivirus or windows update do you have infos on this? any help?
