Overview

Okyo Garde protects devices on your network from becoming infected with malware. If Okyo Garde detects an infected device connected to your network, the malware is blocked from communicating with the attacker and the Okyo Garde app alerts you to the infection so you can take action.

You should remove the malware from an infected device as soon as possible to return it to a healthy status. The steps to remove malware depend on the category of device and operating system. You can also refer to the manufacturer of the device for more guidance.

What does it mean if an infection has been detected on my network?

Infection detection is based on Okyo Garde identifying a connection being made with a host or website that security filters have classified as a command-and-control server.

Command-and-control servers are used by an attacker to infect and communicate with networked devices to use them to attack other devices in the network or to steal information from the infected machine.

Please Note: It is possible that a connection to one of these command-and-control servers can happen prior to a device being infected. In these cases, your device may not actually be infected, so you may want to look for other symptoms of infection before taking the steps outlined below.

How do I know if my device is infected?

These behaviors may be indicators of an infected device:

  • Device has recently become slow, is performing poorly, or is not fulfilling key functions

  • Presence of or increase in pop-ups

  • Presence of search engines you don’t normally use

If you think your device has been incorrectly flagged as infected, please contact Okyo Support: support@okyo.com

Guidelines for removing malware

Smart Devices (IoT)

Smart devices are classified in the following categories: Appliance, Audio & Video, Camera, Gaming, Health & Wellness, Home Automation, Home Security, NAS, Network, Office.

In most cases, the technology built into a smart device is a closed system that can only be cleaned by factory resetting the device. If this is not possible, you may have to replace the device.

  1. Follow instructions for the device to factory reset it. This should restore it to its original like-new state and remove any settings or data that you added or changed. It should also remove any malware.

  2. Ensure the device is running the latest software version available from the vendor. This is typically done via the app or website associated with the device.

  3. Set up the device again after you reset it.
