Solidprotectionspc.com Attempts to Spam Browser Notifications
Solidprotectionspc dot com is a misleading website that exists primarily to spread push notifications and pop-up ads to users' browsers.
The content you will see on Solidprotectionspc dot com will largely depend on your geolocation. In some areas, you might find a blank page, in others, you will see a very different picture. Whenever Solidprotectionspc does not simply put out a blank page, the website will attempt to get users to agree to push notifications in their browser.
This is done using the normal browser interface and the "allow notifications" dialog box. To encourage the user to agree, the prompt is usually combined with some sort of message creating a sense of urgency.
Allowing notifications from similar rogue websites will only lead to an annoying stream of pop-up ads being displayed in the user's browser. Those ads can potentially expose the user to further malware, other misleading sites or questionable content, as a lot of the ads displayed can originate from rogue advertising networks.
The simplest and best thing you can do to stay safe in similar situations is to just close the browser window immediately when an obscure, unfamiliar website asks you to allow notifications. This will ensure your browser is not hijacked by the adware and browser hijackers that similar sites are pushing.
