I am not sure if this is the correct subforum. I choose it because I am a Kaspersky Total Security user.
I noticed that when I activate the Kaspersky extension in either Chrome or Firefox, it adds links to obscure websites to the source code of any website. I see it only when I use the inspector in the browser. Not when I view the page source in a new tab.
An example you can find in the screenshot I made:
Why is this happening?
The moment I turn of the extension, the code is gone.
