File-level scanning of some email servers, backup software, gaming applications, etc. can occasionally cause abnormal system behavior. To exclude specific applications or folders from the ESET NOD32 Antivirus real-time scanner, see the step-by-step instructions below:
NOTE: If the application you are excluding communicates using a network protocol (HTTP, FTP, etc.) you must also follow the steps below:
-
From the Advanced Setup tree, click Antivirus and antispyware → Web access protection → HTTP → Web browsers.
-
If the application you wish to exclude is listed, double-click the corresponding check box. A red "X" will appear. Click OK to save changes—you are finished. If you do not see the application you are trying to exclude, proceed to step 3.

-
Click the Add button to browse and select the .exe file of the desired application. The application will appear in the list of applications to exclude. Double-click the corresponding check box until you see the red "X". Click OK to save changes.
-
Open the main program window by clicking the icon
in the Windows notification area or by clicking Start → All Programs → ESET → ESET Smart Security or ESET NOD32 Antivirus.

Press the F5 key to display the Advanced Setup window.
-

The Add exclusion window will be displayed. Using the directory tree, browse for the folder or file you wish to exclude. The directory path will automatically display In the Exclusion: field. Click OK to save the exclusion.
NOTE: To exclude the contents of an entire drive, the * symbol can be used as a wildcard. For example, to exclude scanning of the entire C: drive, you would enter C:* in the Exclusion: field. To exclude all .doc files from scanning, you would enter C:*.doc in the Exclusion: field. For additional information on the use of wildcards to exclude file/folder scanning, press F1 from the Add exclusion window (Fig. 1-2).
