XM DVR/NVR virus in Digital Video Recorders Posted August 31, 2019 Hi Guys, Last mount we saw that many of XM dvrs and NVR try to auto-update with new firmware and stop works. After restart start to works for 5-10 minutes and again block. We are thinking that this is virus that block XM devices (DVR, NVR, IP cameras) and after update with new firmware problem will solve but on XM web site not new versions of FW. Could you tell me if you have similar problems and how solve them. Thanks in advance!
