I found HitmanPro.Alert the only solutions against HID attacks, "rogue keyboard devices", I made one myself with a cheap 1$ attiny85 that open www.google.com inside browser everytime is inserted into USB : P
I agree that, sometime, I experienced too breakages or other things inside Hitman.Pro Alert, but I found also the protection offered unpaired with other competitors,
in my opinion need take care, but is good software
Don't run the two togehter, there's too much overlap, you're bound to get issues and possibly malware slipping through as they battle each other as to which takes action
If you use HMPA in addition to Windows Defender which these days has great detection, and you'll have very high protection. Otherwise, try Sophos Home Premium if you want more features and which has HMPA integrated (referred to as Intercept X in their product info)
My Webroot licenses expired earlier this year, was hoping for product improvements, but they are still not there and so switched to these other products which are great, but will check Webroot's progress and detection results again at the next licence renewal.
