Stop asking and start reading/learning.
I understand that most of the people ask before read/learn. But, is not my case.
I already read and tried to learn before asking.
Sadly, I am not a genius and have to ask.
I posted same questions in other tech forums and received lot of help, excellent answers, positive feedback etc. I can see my questions are useful.
By the way, sometimes simple questions have simple answers, without need to read/learn an encyclopedia. For example, when talking about MCShield, just mentioning that is an "USB or external drive protection"... would be more than enough! (instead sending tons of pages for reading/learning).
Some replies without simple answers, just commanding people to read/learn... usually indicates lack of knowledge of the own replier.
I appreciate your help, but don't lose your time with me, because I will continue to ask whatever need to ask.
