How to remove Prelandappslab.com ads

Prelandappslab.com can fill up the screen with ads after you click the “Allow” button

Prelandappslab.com is a fake website disguised as a CAPTCHA verification page. It uses social engineering to trick users into subscribing to push notifications. It asks users to press the “Allow” button to supposedly verify if they are not robots. In reality, it starts spamming people with annoying pop-up ads that can appear even when the browser is closed.

Crooks may also use rogue advertising networks that place ads leading to dangerous pages. As a result, people can end up on other scam pages that try to lure out personal information, and fool them into downloading PUPs (potentially unwanted programs),^[1] or malware.

Deceptive tactics

Many people do not know about the social engineering methods that crooks use. A legitimate CAPTCHA verification process should never ask you to choose between “Block” and “Allow” on a browser prompt. Normally, human verification steps ask users to identify certain objects in pictures, like crosswalks, and traffic lights, or to simply check a box. If you see any of these messages be sure to think twice before taking action:

Type Allow to verify that you are not a robot
Click Allow to watch the video
Download is ready. Click Allow to download your file
Press Allow to verify that you are not a robot

Nowadays, crooks do not need to have any hacking skills. All they have to do is come up with a convincing message and image. Always be critical while browsing the web, take it slow, and read everything fully. Do not rush and click the “Allow” buttons without fully understanding the consequences.

Distribution methods

Users rarely find push notification spam pages such as Prelandappslab.com in the search results. Usually, they hide in other shady sites. Be careful of websites that engage in illegal activities as they are unregulated. Illegal streaming platforms^[2] are full of deceptive ads, sneaky redirects,^[3] fake “Download” and “Play” buttons.

Once you click on them, they can open new tabs with harmful websites inside. That is why you should only visit pages that you know and trust. Do not click on random links and buttons. Use legitimate streaming services, like Netflix or Hulu, instead of shady movie platforms.

Another possibility is that the deceptive site appeared without any user input. This can happen if there is adware hiding in your machine. It can cause an increased amount of commercial content, like pop-ups, banners, and redirects without the users' knowledge.

Get rid of cookies and cache

It would be best to avoid shady pages that engage in illegal activities. They can use cookies to track your IP address and geolocation. Websites also have the ability to collect data about your browsing behavior like the websites you visit, searches you make, what you purchase online, etc.

Cookies and cache are small data files stored in your system so they can slow down your device. After you stop the ads from coming, we recommend taking care of your browsers by clearing them. You can do it automatically with FortectIntego. This will delete the information websites have collected about you and will improve system performance.

Scan your system with anti-malware tools

If the previous removal method did not work, you may have adware hiding in your machine. Usually, they sneak into the system from freeware distribution platforms as bundled software. You will have to eliminate the app that is causing the erratic behavior. The problem is that fraudsters often disguise them as “handy” tools to make them more difficult to identify.

Using SpyHunterCombo Cleaner or MalwarebytesMalwarebytes professional security tools would make the process much easier as they can scan the machine and automatically remove the intruders. They can also warn about potential threats before they can make any changes to your computer. However, if you still want to do this yourself, you can follow the instructions below:
