I regularly go on a website called GPXPlus, I have since a month or so after it was created. I was on it yesterday with no issue. When attempting to go on to the site now I'm told that it has been reported as malicious to Opera by some company called "Yandex". I can say with 100% certainty that the site gpxplus.net is in no way involved in malicious activities. I have been a member of that site, and its associated forums, since 2009 and have never had an issue. Any idea why this may suddenly be occurring?
