The ANTI virus infects applications and files resembling applications (such as the Finder). It does not infect the System file. ANTI can infect an application even if the application is not opened. When an application is infected with ANTI, the application’s code is slightly altered and cannot be restored. For this reason, when the ANTI virus is detected, first use CP Anti-Virus to clean the system, then delete the infected applications and reinstall from the original distribution disks.
