Rbtchk11.co[.]in in detail
Rbtchk11.co[.]in claims that it has detected suspicious traffic originating from the visitor's network and states that completing ticking the provided checkbox will verify that the visitor is not a robot. It also displays an image of a robot to give the impression that it is a CAPTCHA or a similar test.

These notifications are designed to appear urgent and instruct users to remove the virus using the provided "Delete Viruses" or "Click to fix" options.
Interacting with these notifications can direct users to scam websites designed to steal money (e.g., by promoting fake or unnecessary services).
