The software is easy to use and navigate through it. I have tried many other softwares like this but they are too technical for me to understand which one works best with my computer. It detects errors that most of them don't detect at all! It has helped me fix some issues in my computer. There's nothing bad about this program as long as you know what your doing when using it. As i said before if you're not familiar with computers then go somewhere else because this will confuse you more than help you. This solves problems such as freezing up or crashing.
