For all other users watching and or with similar issues.
I recommended using
Emsisoft - Emergency Kit: Free Portable Malware Scan and Removal Portable, on his main computer on the network by placing a new folder on desktop "with belief the android does not have a rootkit", downloading and extracting the application in the same folder and launching it from to scan the main hub system on more time. I also recommended a hard reset of the router to flush anything that might be present, and last but not least in these circumstances i recommended some products for checking and prevention.
Traditional antivirus scanners will not detect a virus/malware coming through the network via packets in and out of the devices.
Usually packet sniffers or intrusion detection systems are used to detect these. Many internet security suites have features as such, like Norton, Eset,Kaspersky ect. You can even buy routers with built in security now days to thwart such things.
Packet sniffers like wireshark for example "one of the best" can be used to view/inspect and find the suspected traffic, but will not stop the traffic. Getting an application with IDS/IPS intrusion prevention system is your best bet to stop issues as such. Eset and Norton Security have 2 of the strongest firewalls and IDS/IPS systems on the market. I tested Nortons IDS/IPS frequently back in the day and it flagged attempts of malware even calling out to command and control servers to drop items back onto the system.
With all this information the last thing to add, is checking your accounts, removing as much personal information as possible and control whats divulged past that point.
