For many years watched live streams of cycling on website tiz-cycling.live using an Intel Core i3 PC using Windows 10 OS - Did complete an a Windows Update in the last week which may have caused an issue - Now receive a message to watch live stream please turn off add blocker and refresh screen - My guess this is a problem with Kaspersky Anti-Virus - Note there is no issue using this website on my tablet and phone - And finally no issue using any other website on my laptop.
