requirements. While the Advanced heuristics on executing files from removable media option is enabled, if you wish

4.1.1.1.2 Cleaning levels
Real-time protection has three cleaning levels (to access, click Setup... in the Real-time file system protection section
and then click Cleaning).
No cleaning – Infected files will not be cleaned automatically. The program will display a warning window and allow the
user to choose an action. This level is designed for more advanced users who know which steps to take in the event of
an infiltration.
Standard cleaning – The program will attempt to automatically clean or delete an infected file based on a predefined
action (depending on the type of infiltration). Detection and deletion of an infected file is signaled by a notification the
bottom-right corner of the screen. If it is not possible to select the correct action automatically, the program provides
other follow-up actions. The same happens when a predefined action cannot be completed.
Strict cleaning – The program will clean or delete all infected files. The only exceptions are the system files. If it is not
possible to clean them, the user is prompted to select an action by a warning window.
Warning: If an archive contains a file or files which are infected, there are two options for dealing with the archive. In
standard mode (Standard cleaning), the whole archive would be deleted if all the files it contains are infected files. In
Strict cleaning mode, the archive would be deleted if it contains at least one infected file, regardless of the status of the
other files in the archive.
4.1.1.1.3 When to modify real-time protection configuration
Real-time protection is the most essential component of maintaining a secure system. Always be careful when
modifying its parameters. We recommend that you only modify its parameters in specific cases. For example, if there is
a conflict with a certain application or real-time scanner of another antivirus program.
After installating ESET NOD32 Antivirus, all settings are optimized to provide the maximum level of system security for
users. To restore the default settings, click the Default button located at the bottom-right of the Real-time file
system protection window (Advanced setup > Computer > Antivirus and antispyware > Real-time file system
protection).
