Updated and improved the built in pre-scan tool.

The option “Add .CAT Files (Security Catalog) To Windows Catalog Database” in the pre scan tool is now check marked by default. The reason for this is that if a user had deleted and rebuilt their catroot folder and database then a lot of the cat files would be missing, returning a LOT of bad signatures in the pre-scan.

By having the option checked by default the program will always try to add the cat files back, as long as their signatures are good, back to the database, preventing any false bad signatures.

Updated default permissions for Windows 7,8 & 10 with all updates as of Feb 16, 2016.

Multiple code changes and tweaks.
