I've used Trip Advisor for many years, and have contributed dozens if not hundreds of reviews myself, including for hotels, restaurants and places of interest. While occasionally being led astray (a really awful motel in North Carolina, among the worst places I have ever stayed, was given outstanding reviews and listed as one of the best places to stay in Maggie Valley) it has mostly been a helpful and down to earth website for deciding where to stay and eat while away from home. But today when I attempted to go to tripadvisor.com, my Norton security software stopped me, saying that the website was dangerous, with risks of harm to my computer if I continued. I have no idea why this happened today and not earlier, but wonder if something recently had changed at the website to change it from a safe to a dangerous site. Just thought I would pass this along to any members of the Forum who might not use security software while surfing the web.
