As mentioned, the “ISP HAS BLOCKED YOUR PC” scam has a significant feature that exploits the vulnerability of browsers and could freeze it within 10 seconds tops. Not only that as it turns out, as soon as users get redirected to this scam, it also starts downloading and saving files from the infected computer. The thing is, its latter capability can only be noticed if you’re using a powerful PC but if not it gets away with saving files from your computer. That’s why the majority of the users who reported this scam didn’t notice it.  However, the affected browser that freezes due to the thousands of downloads being saved from the affected computer can be noticed if you open the Task Manager. Because of its ability to freeze browsers, a lot of users were terrified when they encounter this tech support scam. Some were even tricked into calling the fake tech support line. To make it more convincing, it also includes some error codes and uses Microsoft’s name. But you should know better than to fall for its tricks. As you probably noticed, if your “ISP” really blocked your PC, it should mention or state the name of your ISP instead of using this general term. And if you look at the number of your ISP, you’ll find that it’s completely different from the one given in the tech support scam.
