The now-notorious Russian VPNFilter malware, designed to infect several dozen models of home Wi-Fi routers and network-attached storage drives, shows no sign of slowing down. But there's now a test to see whether your router might be infected.

The simple browser-based test, called VPNFilter Check, was developed by antivirus maker Symantec and is on the Symantec website at http://www.symantec.com/filtercheck/. All you need to do is to browse to that site and click the big green button.

One caveat: This isn't a perfect test. It checks for only one component of the VPNFilter malware, the SSLer plugin that knocks a web connection down from encrypted HTTPS to plain old unencrypted HTTP. Other components of the multi-part malware could still be present on your router.

But if your connection does test positive, then you'll definitely need to factory-reset your router, as detailed in our previous article on VPNFilter. We're reproducing the list of routers known to be affected below.
