Thankyou everyone for your responses.
I have switched to Emisoft Antimalware since I had a license of it. With that I have extended my security by adding Zemana Anti Logger beta tester license.
Well I liked your suggestions over backup, but I really do not need a backup program since I have make my own and know what I am creating.
Well most of my files like documents and pictures will stored on OneDrive and the rest large files like videos and music will on my WD HDD.
My SSD is only for Applications and software's. So all the remaining will be covered externally!
