Pragatimeg.com may seem like an innocent website, but it is actually a vehicle for a browser-based tactic. Its main purpose for existing is to deceive unsuspecting users into subscribing to its push notification services. If successful, Pragatimeg.com will then start generating monetary gains for its creators by delivering unsolicited advertisements to the screen of the affected device directly.
The main method of fooling the visitors is through social-engineering tricks. Pragatimeg.com will show several fake alert messages that will pray on people's curiosity, or will simply rely on the users not paying to much attention. For example, visitors may see a black image with a buffering icon accompanied by the text - 'Click Allow to continue.' Following the instructions and clicking t 'Allow' button will not result in any video starting to play. Instead, various unwanted advertisements promoting dubious adult websites or fraudulent software update will start taking up space on the device's screen. In most cases, closing the browser will not be enough to stop the advertisements from appearing.
What victims of this scheme have to do is not that complex. Just open the 'Settings' menu of the affected browser, scroll down to the 'Permissions' section, and remove all permissions granted to any sight that might be deemed as suspicious.
