What are Au01.bid 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 Au01.bid notifications is the malignant origins of the latter. Common pop-up advertisements are offered for you to enable on different sites with a understandable purpose – notify you about the latest articles, discounts and so on. It is an effective approach to help your site to keep visitor’s attention and help the interested visitors to have the best price.

Brief description of the Au01.bid pop-ups:

Au01.bid pop-up ads, as opposed, have a deal with less legit sites. You will generally witness the offer to enable them following the redirection from another site. There’s nothing bad in redirecting unless they throw you into such a dubious place. In this case, enabling pop-ups is offered under the guise of the anti-DDoS check-up. Alternatively, the sites can refuse to show you the contents unless you apply these pop-ups. These demands should already raise suspicion, as sites usually feature a less obscure anti-bot mechanism. Spectating such an demand is a reason to skip the website right away. In some cases, even after clicking “Allow”, you will not get to the web page – the sole page it has is a landing page with the offer to turn on the pop-up ads.

Au01.bid push notification.

How does it work?

Most of browsers support turning on pop-ups from sites. Websites, on the other hand, may send notifications with the content they like. It may be an advertisement of the product or a page published on this particular website, as well as a promotion of their partner page. As a result, you may see the push notification from site X, but interacting with it will redirect you to website Y – because a referral link to the latter was added.

Cyber burglars bear on this feature in their attempt to earn money through advertising. They trick users into allowing the pop-ups, and after that just spread hundreds of banners of anyone they contract with. As you may suppose, no benevolent companies will have a business with fraudsters. All the Au01.bid popups you may see lead to other untrustworthy sites. In some cases, the same victim can 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 commonly provides a negligible pay for one view, but when you can send ads to a huge number of users and make it hundreds of times each day – that is a much more significant sum. Despite most of these banners giving no result at all, it can still give all the participants a lot of money.

Are Au01.bid pop-up advertisements dangerous?

Yes, they are. At the surface, they can look harmless – just a blinking window that appears from time to time. However, the things this window promotes differ drastically from what you generally see in push notifications. Au01.bid web page is controlled by crooks, who deliberately show hundreds of irrelevant ads in pop-ups. They also don’t follow any common sense and can make sporadic pop-up advertisements into a storm of ads. For weak systems, that may be enough to cause performance issues. But that is not all problems these pop-up ads carry.

As with any other thing that touches illegal advertising, Au01.bid pop-ups lack legit offers. Even when crooks make the banners looking similar to ones from well-known retailers, the site these banners will throw you to are completely different. And these pages can 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 advertisements 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, Au01.bid push notifications are not recommended to click on either, and the best solution is to disable them as soon as possible.

How to remove Au01.bid pop-ups?

Fortunately, Au01.bid push notifications removal is not very complicated. They sit in the browser and can’t hide themselves among system files. However, as I pointed out above, some pop-up advertisements can promote malicious programs to your system. It is hard to describe all cases, and manual attempts to remove malware is a poor idea. For that reason, after removing the source of the pop-up advertisements it is recommended to use anti-malware software. I’d especially recommend that in the case when you have never allowed push notifications, and they still appeared. This situation may be a sign of malware activity. GridinSoft Anti-Malware will perfectly fit both system recovery and malware removal purposes, thanks to its system recovery functionality and multi-component detection system.

First of all, you should reset your browser settings. It is possible to accomplish in both manual and automatic manner. The former, obviously, takes more time to complete and can be somewhat complicated if you have never done that.
