Comcast's Xfinity internet customers have been reporting multiple websites, including PayPal, Steam, and TorrentFreak have been getting blocked by the ISP's "protected browsing" setting. From a report: The "protected browsing" setting is designed to "reduce the risk of accessing known sources of malware, spyware, and phishing for all devices connected to your home network." This, in general, isn't a bad thing. It's similar to Google Chrome's security settings that warn you when you have an insecure connection. But it's odd that Xfinity's security setting would be blocking perfectly harmless sites like PayPal. Multiple consumers have been reporting on Comcast's forums and elsewhere that they've been blocked while trying to access sites that many people use every day. After posting about it on the forums, one user who said they couldn't access PayPal said the problem with that particular site had been fixed.
