The ‘Checking visitor’ pop-ups may be displayed when users are redirected to a Web server programmed to display ads to visitors. Often, seeing the ‘Checking visitor’ Pop-Up may not mean that you have something fishy installed on your computer, but in some scenarios, it might turn out that the reason why you are seeing the ‘Checking visitor’ pop-ups is that you have adware installed on your computer. We are yet to hear of the ‘Checking visitor’ pop-ups being associated with any unsafe content, but this does not mean that you should trust the advertisements they display.

Although it is quite unlikely that the ‘Checking visitor’ pop-ups are caused by adware, we advise people who see these pop-ups to run their favorite anti-malware scanner to make sure that there isn’t any suspicious software present on their computers.

The ‘Checking visitor’ pop-ups often may promote various products and services, but it is possible that they might lead users to unreliable websites, which might be used to run fraudulent schemes or hoaxes. If you ever come across ‘Checking visitor’ pop-ups, we advise you to close them immediately, as well as to close all tabs and pages related to them.
