I see that I am not the first with this issue so hopefully there is already an established fix. I receive the red pop up box with Malicious URL blocked warning. the objects change and the warning seems to be pretty much continuous. I first started to get this in July and have since tried to update everything i have with no effect on the pop up. everything seems to run OK. I use both explorer and mozilla. Please help.
follow this guide and attach the logs…not copy and paste
