What are Theextensionexpert pop-up notifications?

As the pop-up definition goes, these are short and small advertisements that attract your attention to a product they promote. But the difference between regular pop-ups and Theextensionexpert pop-ups is the malicious origins of the latter. Common pop-up ads are offered for you to enable with a legitimate purpose – notify you about the fresh posts, goods for sale and so on. It is a useful tool to help your site to keep visitors and help the interested users to have the best deal.

Brief description of the Theextensionexpert.com pop-ups:

Theextensionexpert push notifications, in contrast, have a deal with untrustworthy web pages. You will generally see the proposition to enable them following the redirection from another page. It’s OK to see redirects unless they throw you into such a questionable place. In this case, turning on pop-up ads is served as the anti-bot check-up. In other cases, the sites can refuse to show you the contents unless you turn on these pop-up ads. These demands should be the red flag, as websites usually have a more convenient anti-bot mechanism. Seeing such an requirement should be the reason to leave the page doubtlessly. Sometimes, even when you click “Allow”, you will not see the web page – it has only a landing page with the offer to turn on the pop-up notifications.

How does it work?

Most of browsers support turning on push notifications from sites. Sites, on the other hand, can send notifications with the content they want. It may be a promotion of the product listed on this particular website, as well as a promotion of the page of their partner. As a result, you can see the pop-up from site X, but clicking it will redirect you to website Y – because a referral link to the latter was built in.

Scoundrels bear on this ability in their attempt to earn money using illegal advertising. They trick victims into allowing them to show the banners, and after that just spread numerous promotions of anyone they have a deal with. As you may suppose, no legit companies will have a deal with fraudsters. All the Theextensionexpert popups you may see lead to other untrustworthy sites. In some cases, the same victim may get into a trap of multiple pop-up spamming websites, and its browser will turn into a complete mess.

The banners these rascals show are paid under the pay-per-view model. It generally provides a negligible pay for one person, but when you have hundreds of victims and show them hundreds of ads each day – that is a much more significant sum. Despite most of such banners are ineffective, it may still bring all the parties a lot of money.

Are Theextensionexpert pop-ups dangerous?

Yes, they are. Initially, they can look non-threatening – just a colourful pop-up that appears from time to time. However, the things this window promotes differ sharply from what you used to see in push notifications. Theextensionexpert.com web page is controlled by crooks, who intentionally throw hundreds and thousands of malicious ads in pop-ups. They also never follow any common sense and can make sporadic push notifications into a hurricane of banners. For weak systems, that may be enough to cause performance issues. But problems are not over at this point.

As any other thing that touches illegal advertising, Theextensionexpert push notifications don’t have legit deals to offer. Even though crooks make the ads looking similar to ones from Walmart or Amazon, the web page 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 pop-up ads 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, Theextensionexpert pop-up advertisements are not recommended to click on either, and the best solution is to disable them as soon as possible.

How to remove Theextensionexpert pop-ups?

Fortunately, Theextensionexpert pop-up ads removal is not very complicated. They parasite in the web browser and cannot conceal themselves among system files. Nevertheless, as I stated above, some pop-up notifications may deliver malicious programs to your computer. It is nearly impossible to show all cases, and manual malware removal is inconvenient. Therefore, after disabling the pop-up notifications the best option is to use anti-malware software. I’d especially recommend that if you have never clicked “Allow” to pop-up ads, and they still appeared. That may point at malware activity. GridinSoft Anti-Malware will be the best both system recovery and malware scanning purposes, thanks to its system recovery functionality and superb detection system.

First of all, you should reset your browser settings. You can do that in both manual and automatic manner.
