If you keep seeing different advertisements in the browser, such as “Windows key code is not valid and seems pirated” pop-ups, banners, or other ads, then an adware program is installed on your computer. “Windows key code is not valid and seems pirated” is a website that misleads people by redirecting the browser to a online tech support scam.
Therefore, the purpose of “Windows key code is not valid and seems pirated” is to make money by redirecting users to websites that scam users. The more website traffic gets, the more money the developers can make.

Any browser redirects that adware may cause can then redirect the browser to other websites that offer or attempt to install malware. Therefore, I advise you to check your computer for malware like adware. This is because “Windows key code is not valid and seems pirated” is a part of, in this case, adware that can cause many online problems, including serious identity fraud.

If you suspect adware has been installed on your computer, you often recognize the following symptoms:

1. Unknown popup(s) from an unknown website. When you see unfamiliar popups, especially when using the browser, this is a sign that adware has been installed on your computer.
2. The homepage or new tab has been changed without your permission. If a new home page is suddenly set in your default browser, this is also a sign of adware or possibly malware.
3. Unknown browser redirects. Check your computer for adware if the browser suddenly opens new windows or tabs when you click a hyperlink.

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.

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.
