Learn about intruders and how to keep your PC and network safe
We display this alert when a PC or device—that you've previously marked as an Intruder—tries to reconnect to your network.
To trust this PC or device, you must unmark it as an Intruder. Do one of the following:
- From the alert, click Manage My Network, and then unmark it as an Intruder.
- Open your McAfee software, expand the Home Network Defense drawer, click Home Network, and then follow the on-screen instructions.
Yes—as long as your McAfee software security status displays that you are protected and up to date, then you're protected from viruses, spyware, and other threats, and your protection is up-to-date.
If the PCs on your network have updated McAfee software installed on them, then you're protected from intruders. However, your network and other PCs or devices, such as printers, may be vulnerable to intruders. To protect your network or other PCs, please do this:
Protect your network by enabling WPA encryption on your wireless router. Encryption scrambles your data so intruders can't access it. You can learn how to enable and configure WPA encryption for your network by visiting your router manufacturer's website, or by referring to your router's documentation.
Protect other PCs on your network with McAfee software. You can go to the PC that you want to protect, log in to your McAfee account, and follow the on-screen instructions to download and install your McAfee software on that PC.
