As it continues to investigate the VPNFilter malware that's gripped hundreds of thousands of routers worldwide, the FBI has advised consumers and office managers in the US to reset their network boxes to try and flush out at least part of the malicious code.

"The FBI recommends any owner of small office and home office routers power cycle (reboot) the devices," the Bureau said in a statement. "VPNFilter is able to render small office and home office routers inoperable. The malware can potentially also collect information passing through the router."
