Device control

ESET NOD32 Antivirus provides automatic device (CD/DVD/USB/...) control. This module allows you to block or adjust extended filters/permissions and define a users ability to access and work with a given device. This may be useful if the computer administrator wants to prevent the use of devices containing unsolicited content.

Supported external devices:

Disk Storage (HDD, USB removable disk)


USB Printer

FireWire Storage

Bluetooth Device

Smart card reader

Imaging Device


LPT/COM port

Portable Device

All device types

Device control setup options can be modified in Advanced setup (F5) > Device control.

Enable the slider bar next to Enable Device control to activate the Device control feature in ESET NOD32 Antivirus; you will need to restart your computer for this change to take effect. Once Device control is enabled, the Rules will become active, allowing you to open the Rules editor window.


You can create different groups of devices for which different rules will be applied. You can also create only one group of devices for which the rule with action Read/Write or Read only will be applied. This ensures blocking unrecognized devices by Device control when connected to your computer.

If a device blocked by an existing rule is inserted, a notification window will be displayed and access to the device will not be granted.
