Detection exclusions

Detection exclusions allow you to exclude objects from cleaning by filtering the detection name, object path or its hash.


example

Detection exclusions do not exclude files and folders from scanning as Performance exclusions do. Detection exclusions exclude objects only when they are detected by the detection engine and an appropriate rule is present in the exclusion list.

For example (see the first row on the image below), when an object is detected as Win32/Adware.Optmedia and the detected file is C:\Recovery\file.exe. On the second row, each file, which has the appropriate SHA-1 hash, will always be excluded despite the detection name.

CONFIG_EXCLUDE_DETECTION

To ensure that all threats are detected, we recommend creating detection exclusions only when it is absolutely necessary.

To add files and folders to the exclusions list, Advanced setup (F5) > Detection engine > Exclusions > Detection exclusions > Edit.

To exclude an object (by its detection name or hash) from cleaning, click Add.

For Potentially unwanted applications and Potentially unsafe applications, the exclusion by its detection name can also be created:

In the alert window reporting the detection (click Show advanced options and then select Exclude from detection).

From the Log Files context menu using Create detection exclusion wizard.

By clicking Tools > Quarantine and then right-clicking the quarantined file and selecting Restore and exclude from scanning from the context menu.

Detection exclusions object criteria

Path – Limit a detection exclusion for a specified path (or any).

Detection name – If there is a name of a detection next to an excluded file, it means that the file is only excluded for the given detection, not completely. If that file becomes infected later with other malware, it will be detected.

Hash – Excludes a file based on a specified SHA-1 hash, regardless of the file type, location, name, or extension.

Control elements

Add – Add a new entry to exclude objects from cleaning.

Edit – Enables you to edit selected entries.

Delete – Removes selected entries (CTRL + click to select multiple entries).

Import/Export – Importing and exporting of detection exclusions is useful if you need to backup your current exclusions for use at a later time. The export settings option is also convenient for users in unmanaged environments who want to use their preferred configuration on multiple systems, they can easily import a .txt file to transfer these settings.

Detection exclusions setup in ESET PROTECT

ESET PROTECT 8.0 includes a new wizard for detection exclusions management—create a detection exclusion and apply it to more computers/group(s).

Possible detection exclusions override from ESET PROTECT

When there is an existing presence of a detection exclusions local list, the admin has to apply a policy with Allow appending detection exclusions to locally defined list. After that, appending detection exclusions from ESET PROTECT will work as expected.
