When either the main Trojan Remover program, the FastScan, or the Updater program are started, Trojan Remover carries out an internal check of all its core program files. This is a very important step in ensuring that the files have not been tampered with or virally infected. It is recommended to leave this option enabled.
On occasions these checks can take some time (often because a firewall needs to be told to grant permission for Trojan Remover to access the Net). If you find that the delay caused by Integrity Checking is too great you can disable this option by starting Trojan Remover and selecting Options. Click on Integrity Checking enabled to turn this option off. Note: this will mean that, if any of Trojan Remover's program files are compromised, Trojan Remover will be unable to alert you. To turn this option back on click on Integrity Checking disabled.
