threat defense

Recently, my computer is always the problem, I do not know how, when this morning, I opened the computer to see, I found that many of the files are a problem, that caught my attention, so I quickly find someone to give me repair, and then they gave me to install a threat defense software, he told me that there is the threat defense software, then there will not be such a problem, heard him say this, I won’t have to worry about, then I also studied the threat defense software I, although that is not how to understand, but look very good, wait to have time, I want to take on the threat defense software to do some research.
