Constant pop ups re blocked websites
I'm using Trend Security Software on my Dell PC (Microsoft s/w) essentially to check for viruses. In the last few weeks I've also been getting Trend pops warning me about a suspicious website that should not be opened. It's annoying because it happens every minute or two or even more frequently. I have to close the pop up each time to be able to continue with other work I'm doing on the PC. I don't recognise the website concerned and I've no idea where it's coming from. How do I eliminate these pop ups?
