Do NOT try Cucusoft Netguard. I installed it, it didn't work, so I uninstalled it, and it left a zombie process on my machine - C:\Program Files\Cucusoft\NetGuard\SysMsgProxySrvc.sys, and entries throughout the registry - startup, services, everywhere. Because it is tied into my network stack I am now concerned that force-removing it will cause problems somewhere. There was another that installed a filter into every network connection on my machine. When I uninstalled the software, every connection died.
Just a word of warning. I've posted requesting assistance for removing Cucusoft over on this post
I am using DUMeter for (i think) 3-4 years now. Even now with flat optic cable internet (where i dont have a lot of use for this program) it seems i can not get rid of this awesome tool .
