looks like you have an outdated version installed and also outdated information or strategy for McAfee products.
Regarding the update, you have an outdated product which is already EOL, therefore you will not get any new signatures. Additional, new signatures are not tested with the product any more.
Just some hints from my side. :-)
If you are using Windows 10 RS2 you need at least Virusscan Enterprise 8.8 P9. But, you should not use the legacy products any more. The better joice is to install Endpoint Security 10.5.1. This version also includes most parts of the HIPS product. The feature is called Exploit prevention.
