Besty-deals.com is yet another dubious website created with the sole purpose of delivering questionable content to its visitors while trying to carry out a popular browser-based tactic simultaneously. The exact behavior of the site is based on the geolocation of the user. Besty-deals.com ascertains this by accessing the visitor's IP address. It can then either start displaying content on its own page or redirect to other unreliable third-party websites.
At the same time, Besty-deals.com might use misleading and deceptive alert or warning messages to trick users into subscribing to the site's push notification services. The exact scenario may change but the website has been observed pretending to perform a fake CAPTCHA check for bots. It shows an image of a robot accompanied by the message - 'Click Allow if you are not a robot.'
Doing so will grant the unsafe website broad browser permissions that it will then abuse to run intrusive advertising campaigns. The advertisements could continue to appear on the screen of the affected device even if the Web browser itself has been closed. Users are not encouraged to interact with the generated advertising materials, as they could lead to unsafe websites.
Landing on dubious websites such as Besty-deals.com could be a symptom of a PUP (Potentially Unwanted Program) lurking on your device.
