7: Automatically examining removable media when it is appended to the PC

Similarly as these projects check PC programs when they are opened and downloads before they are allowed on the PC, they additionally naturally examine streak drives and other removable media at whatever point they are associated with the PC.

8: Blocking programmers from getting to the PC
