Download and installed with a little bit hesitation because I don’t know much about this software and vendor company. I only used the other software in this category like System Mechanic,Advanced System Care,Glary Utilities,Kerish Doctor,Wise Care 365 and many more.The first Scan took about thirty minutes to complete and I repair all the problems then reboot my Windows 7 64bits machine. Oh Yes!!! It works-really works-GREAT-My God I don’t believe that actually this is my computer or any body else.Now my laptop run like a Rabbit and what a blazing internet speed now. Ultimately I am very much impressed by this software and in my opinion this software deserves 5 out of 5 stars. Thanks Ashraf and Large Software for this great software as a Gift.
