IF10 is a protected file and cannot be tampered with easily. If the file is altered in any way the program will refuse to run stating that it has been altered.
When a program is installed, administrator rights are required to set up the installation.
IF10 installation checks first for tampering with the file and exits if it is deemed unsafe.
If the file is safe the program wants to switch into admin mode and asks the user to choose OK to continue. IF10 then re-launches in admin mode for the installation. Once IF10 is installed no admin privileges are required to run the program normally.
It is this increased level of design that ensures IF10 will not allow malware to be installed on your system.
