Hello   @ConnerEichmann 

The AP200 is a Wifi access point connected to router to extend Wi-Fi connection, but not the router/ gateway in the network, can you double-check the Antivirus software gives warning for the AP200 or router in the network? If the warning is for router,  you might reach router support. 

If AP stopped working or has no internet connection, try to test connect a PC to the router directly using the same Ethernet cable and confirm router has internet. 

Please also confirm Access Point or Router is on the latest firmware, If the same, can I know what is exact warning or message on the antivirus software? Please provide a photo of it, thank you.
