Hopsigna.com

Hopsigna.com is a useless website that displays a fake error message to trick users into subscribing to its browser notifications. The misleading pop-up window contains the following text:

"Hopsigna.com wants to Show notifications

 Press 'Allow' to confirm push-notifications!"

Never click on the "Allow" button, because, doing it, this unsafe tool will start flooding you with unwanted advertisements for adult content, gaming websites or fake software updates. These advertisements will appear on your screen even if you have not launched an Internet browser, and they could contain threatening links infected with malware.

Seeing Hopsigna.com pop-ups on your device also could be a symptom of an adware infection. In that case, you also may notice that your browser has been hijacked, and its homepage, new tab settings, and default search engine have been changed automatically. It may be difficult to remove an adware program manually, so experts advise using an automated malware removal tool.
