For the past week while browsing Railforums.co.uk using the Internet browser on my Samsung Galaxy J5 phone I have on a few occasions been redirected to wiserapps.site and bombarded with pop-up messages telling me that my phone is severely infected with viruses and encouraging me to download their anti-virus software. It's not possible to navigate back from this site and I have to close my browser. I am only experiencing this issue on Railforums.co.uk and not any other website. Is anyone else experiencing this issue? Is something wrong with my phone or something wrong with Railforums.co.uk?
