I started out using TF, but after reading about Mamutu I bought 3 licenses. I have since removed all 3. The problems were at boot. For some reason some of my other security programs didn't want to load. Then I would find out that Mamutu had them tied up. Never had this problem with TF. And what was really bad ,Mamutu was sneaky. It didn't give any indication. But when I would try to re-boot I would get a pop up saying Mamutu Alert didn't want to shut down. Has anyone else had this problem?
