Ads by the Review4.in site are not legitimate either. At best, those will be completely unrelated banners, that will still be annoying considering their frequency. However, more frequent cases involve advertisements of enigmatic deals with 90% discount, adult sites ads or scam attempts. Here are some of the traditional patterns for pop-up spam:

Where did Review4.in pop-ups come from?

The primary and most prevalent method to access the pop-up spamming site is to explore content on warez sites, pages containing pirated content, and similar platforms. The persons responsible for such dubious venues aim to compensate for expenses via redirects, often as a promotion tactic. This type of redirection is commonly known as an “anti-bot verification”.

An extra plausible source of pop-up advertisements is adware, currently active inside your system. It changes browser settings in a way so it starts displaying Review4.in pop-ups without your consent. However, this situation is relatively infrequent, as such malware employs its own, more productive approach to showcasing advertisements.

Are Review4.in pop-up advertisements dangerous?

Yes, they are. At the surface, they may look non-threatening – just a colourful window that appears a couple times in an hour. However, the contents of this window differ sharply from what you generally see in pop-ups. Review4.in web page is ruled by fraudsters, who intendedly throw tons of irrelevant ads in pop-ups. They also don’t follow any manners of advertising and can make sporadic pop-ups into a storm of ads. For weak systems, that may be enough to make the system slower. But that is not all problems these pop-ups carry.

As any other thing that touches illegal advertising, Review4.in push notifications lack legit deals to offer. Even when crooks make the banners looking similar to ones from Walmart or Amazon, the website these ads will throw you to are completely different. And these pages may offer you to turn on other pop-ups, install a “useful” program, or pay for a thing at a big discount and never receive it. Let’s leave aside the cases when push notifications promote phishing pages or straightforward malware. There’s no way these pages will bring you any good, thus interacting with them is a very bad idea. For the same reason, Review4.in pop-ups are not recommended to click on either, and the best solution is to disable them as soon as possible.

# entry should be kept on an individual line. The IP address should

# space.

# lines or following the machine name denoted by a '#' symbol.
