What are ShortUrl.ac push 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-up advertisements and ShortUrl.ac notifications is the malicious origins of the latter. Common push notifications are offered for you to enable with a understandable purpose – keep you aware about the latest articles, discounts and so on. It is a useful tool to help your website to keep visitor’s attention and help the interested ones to have the best deal.

Brief description of the Shorturl.ac pop-ups:

ShortUrl.ac pop-up advertisements, in contrast, have a deal with unlegit web pages. You will generally see the proposition to enable them following the redirection from another page. There’s nothing bad in redirecting unless it throws you to such a dubious place. At that point, enabling pop-up ads is offered under the guise of the anti-bot check-up. Alternatively, the sites can deny showing you the content unless you enable these pop-up advertisements. These requirements should already raise suspicion, as websites generally have a more convenient anti-bot mechanism. Spectating such an demand should be the reason to skip the page right away. Sometimes, even when you click “Allow”, you will not see the site – it has only a landing page with the offer to turn on the push notifications.

How does this work?

Most of web browsers support turning on push notifications from websites. Sites, on the other hand, can send notifications with the content they like. It may be a promotion of the product posted on this site, or an ad of their partner page. As a result, you may see the pop-up from site X, but interacting with it will redirect you to site Y – because a referral link to that website was embedded.

Crooks bear on this ability in their approach to earn money using illegal advertising. They trick victims into allowing the pop-ups, and then just spread hundreds of banners of anyone they contract with. As you can suppose, no legit organisations will have a business with fraudsters. All the ShortUrl.ac popups you may see lead to other fraudulent sites. At some point, the same user may get into a trap of multiple pop-up spamming sites, and its browser will turn into a complete mess.

The banners these crooks show are paid under the pay-per-view model. It usually provides a negligible commission for one viewer, but when you have hundreds of victims and show them hundreds of ads every day – that is a way bigger sum. Even though most of such banners giving no result at all, it can still give all the parties a lot of money.

Are ShortUrl.ac pop-up ads dangerous?

Yes, they are. Initially, they may look non-threatening – just a colourful window that appears from time to time. However, the contents of this window differ sharply from what you used to see in pop-up advertisements. Shorturl.ac site is controlled by fraudsters, who intentionally throw hundreds of irrelevant ads in pop-ups. They also never follow any manners of advertising and can make sporadic pop-ups into a storm of ads. For weak computers, that may be enough to cause performance issues. But troubles are not over at this point.

As with any other thing that touches illegal ads, ShortUrl.ac push notifications lack legit offers. Even though crooks make the ads looking similar to ones from well-known retailers, the website these banners 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 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, ShortUrl.ac 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 ShortUrl.ac pop-ups?

Fortunately, ShortUrl.ac pop-ups removal is pretty easy. They sit in the web browser and cannot conceal themselves on a disk. Nonetheless, as I pointed out above, some pop-up ads may introduce malware to your computer. It is nearly impossible to describe all of the cases, and manual malware removal is inconvenient. For that reason, after removing the source of the pop-ups it is recommended to use anti-malware software. That is especially recommended in the case when you have never allowed pop-ups, and they still appeared. That may be a sign of malicious software activity. GridinSoft Anti-Malware will be the best both recovery and malware removal purposes, because of its abilities of system recovery and multi-component detection system.
