Their objective is to trick users into engaging with these notifications, which can result in unfavorable outcomes. One prevalent purpose of these deceitful push notifications is to drive traffic toward scams or phishing websites designed to illicitly obtain personal information or infect the user’s device with malware.

Furthermore, these notifications serve as a means to promote unwanted or malicious software by deceiving users into downloading or installing it. This can include adware, spyware, or other malicious software that compromise the user’s device and privacy. In certain instances, these fake push notifications generate revenue for malicious advertising networks by enticing users to click advertisements or subscribe to paid and potentially malicious online services.

It is crucial to remain alert and cautious when encountering push notifications from suspicious sources like Re-captha-version-3-21.top.

Step 3: Uninstall adware software

In this second step, we will check your computer for adware software. In many cases, adware is installed by you as a user yourself. This is because adware is bundled with other software you can download for free from the Internet.

Adware is then offered as a helpful tool or an “offering” during installation. If you do not pay attention and quickly click through the installation process, you will install adware on your computer. Thus, this is done misleadingly. If you want to avoid this, you can use Unchecky software. Using the steps below, check for adware installed on your computer and remove it.

Windows 11

  1. Click on “Start.”
  2. Click on “Settings.”

Step 4: Scan your PC for malware

Now that you have uninstalled adware apps, I advise you to check the computer for any other malware for free.

It is not recommended to remove malware manually because it can be difficult for non-technical people to identify and remove all the traces of malware. Manually removing malware involves finding and deleting files, registry entries, and other often hidden details. It can damage your computer or leave it vulnerable to further attacks if not done correctly. So, please install and run the malware removal software, which you can find in this step.
