TI File Integrity Software

This tab is dedicated to the file tracking capabilities of this program. Unlike the previous version of this program, which would show you only tracked programs and would only allow you to track all programs on your device, this utility allows you to see a list of all programs on your device and to individually choose which files to track. While the list of programs, by default, is limited to only protected programs you can expand this include all programs and even application variables using the Settings tab.

Looking at the program list within this tab will show you whether tracking is active on that particular file or not. Tracking being active is denoted by a blue magnifying glass type icon to the left of the file's name. "Tracking" means that this file has integrity data on it saved. This information includes a 4-byte checksum (increased from 3 bytes in the previous version), the name of the file, the file's size, and the file's type.

From within this tab, you can use some keys to interact with the files on your calculator. Press the 2nd key to activate tracking on a selected file and the Del key to deactivate tracking on the file. Press the Stat key to refresh the list and X,T,θ,o to initiate an integrity verification. In an integrity verification, first the current attributes (size and checksum) of a file are checked against the attributes stored in the tracking file. If both match, then the file is shown as good and the check proceeds to the next file. If a file fails the attribute check the file is shown as modified. A file that returns modified is then automatically checked for malware using the malware definitions file (if installed). If the file passes the malware check, it is shown to be clean and you are given the option to update the tracking data for the file. If the file fails the malware check, you are informed that the file is infected and are given the option to move the file to Quarantine (see Quarantine tab). You will also be able to perform a malware scan on an individual file using the Prgm key.
