How to remove Notifsystems.com ads

Notifsystems.com can cause annoying pop-up ads to start appearing on the screen

Notifsystems.com is a spam page created by crooks. It uses social engineering methods^[1] to trick people into subscribing to push notifications. Users are asked to press the “Allow” button to confirm that they are not robots. However, what ends up happening instead is spam.

Annoying pop-up ads start showing up on the screen even when the browser is closed. Unfortunately, crooks may use rogue advertising networks that place ads leading to dangerous websites. People can end up on pages that try to lure out personal information, trick them into downloading PUPs (potentially unwanted programs),^[2] and malware.

Typically, users describe seeing ads promoting adult pages, fake antivirus deals, software offers, surveys, and giveaways. That is why it is so important to disable the ads as soon as possible, especially if there are other people using the affected machine.

Distribution methods

Push notification spam pages created by fraudsters can rarely be found in the search results. Generally, they are hidden on other shady sites that are unregulated. Such pages are full of deceptive ads and sneaky redirects. For example, illegal streaming sites may display fake “Download” and “Play” buttons which are actually ads that open new pages.

That is why it is best to only visit websites that you know and trust. Do not click on random links and ads even if they seem to be promoting legitimate products. Crooks could be using social engineering to lure you in. It is always best to go to the source directly.

Adware infections

In some cases, the ads may not be caused by a single rogue website. It can be a result of an adware^[3] infection. It is advertising-supported software that causes an increased amount of commercial content, like pop-ups, banners, and redirects on the machine.

PUPs like this, are most often spread through freeware distribution platforms. We recommend only using official web stores and developer sites for software installations. You should also always choose the “Custom” or “Advanced” installation methods, and check the file list. Untick the boxes next to any unrelated applications.

Cookies and cache

Almost all websites nowadays require you to accept cookie^[4] usage. Because you experienced pop-up spam caused by a fake site, there is a big chance you were browsing through questionable pages that could still be tracking your browsing activity.

Cookies can store data such as the websites you visit, links you click on, things you search for, and what you purchase online. It can later be sold to advertising networks or other third parties. We recommend using a repair tool like FortectIntego, which can automatically clear your browsers from cookies and cache, clear up space, fix corrupted files, system errors and optimize the performance of the device.
