If a considerable time interval has elapsed between the moment you had removed an older version and the moment you had installed a newer one, we recommend that you abstain from using the iChecker database saved since the previous installation of the application. During this time interval, a malicious program may have penetrated into your computer and taken malicious actions that cannot be detected with this database, which may eventually lead to the infection of your computer.
If you re-install the application due to components malfunctioning, then in order to eliminate your problem, it is not recommended to save the application operating settings.
