For last few weeks I have been getting a script error message on my Windows 8 Desktop. UNSUPPORTED OS ERROR. After much discussion with Microsoft community I have run full virus and malware scans no problems. Disabled Java add-ons because of potential security risk. All to no avail. The error seems to arise from a http with an address containing Motive which I have discovered is to do with Plusnet Wireless. Although I use an Ethernet connection. Is this important? does anyone else get it ? How can I get rid of it?
