Open the main program window of your ESET Windows product.
Click Setup → Internet protection.
Click the slider bar next to Antispam protection to disable it.
Click the drop-down menu on the left side, select for how long the Antispam protection will be disabled and click Apply.
To re-enable Antispam protection, click Enable Antispam protection in the main program window (Home).
Alternatively, you can click Setup → Internet protection and click the slider bar next to Antispam protection to enable it.
