Did you just get a pop-up from w3.css-validator.org and wonder where it came from? Did the w3.css-validator.org ad appear to have been initiated from a web site that under normal circumstances don't use advertising such as pop up windows? Or did the w3.css-validator.org popup show up while you clicked a link on one of the major search engines, such as Google, Bing or Yahoo?
Here is a screenshot on the w3.css-validator.org pop-up from my system:
(I'm sorry for the many watermarks. If I don't add them, the screenshot always show up at some copy-cat blogs.)
If this sounds like what you are seeing on your machine, you most likely have some adware installed on your machine that pops up the w3.css-validator.org ads. So don't write angry emails to the web site you were browsing, the advertisements are presumably not coming from them, but from the adware on your system.
I'll try help you to remove the w3.css-validator.org popups in this blog post.
I found the w3.css-validator.org pop-up on one of the lab systems where I have some adware running. I've talked about this in some of the previous blog posts. The adware was installed on purpose, and from time to time I check if something new has appeared, such as pop up windows, new tabs in the browsers, injected ads on site that usually don't show ads, or if some new files have been saved to the hard-drive.
So, how do you remove the w3.css-validator.org pop-up ads? On the machine where I got the w3.css-validator.org ads I had adware installed. I removed those adware programs with FreeFixer and that stopped the w3.css-validator.org pop-ups and all the other ads I was getting in Firefox.
The issue with popups such as this one is that it can be popped up by many variants of adware, not just the adware running on my system. This makes it impossible to say exactly what you need to remove to stop the pop-ups.
So, what can be done to solve the problem? To remove the w3.css-validator.org popup ads you need to check your machine for adware or other types of unwanted software and uninstall it. Here's my suggested removal procedure:
The first thing I would do to remove the w3.css-validator.org pop-ups is to examine the programs installed on the machine, by opening the "Uninstall programs" dialog. You can open this dialog from the Windows Control Panel. If you are using one of the more recent versions of Windows Operating System you can just type in "uninstall" in the Control Panel's search field to find that dialog:
Click on the "Uninstall a program" link and the Uninstall programs dialog will open up:
Do you see something suspicious listed there or something that you don't remember installing? Tip: Sort on the "Installed On" column to see if something was installed about the same time as you started observing the w3.css-validator.org pop-ups.
Then I would check the browser add-ons. Adware often appear under the add-ons menu in Google Chrome, Mozilla Firefox, Internet Explorer, Safari or Opera. Is there anything that looks suspicious? Anything that you don't remember installing?
I think you will be able to identify and remove the adware with the steps outlined above, but in case that did not work you can try the FreeFixer removal tool to identify and remove the adware. FreeFixer is a freeware tool that I started develop many years ago. Freefixer is a tool built to manually identify and uninstall unwanted software. When you've found the unwanted files you can simply tick a checkbox and click on the Fix button to remove the unwanted file.
FreeFixer's removal feature is not locked like many other removal tools out there. It won't require you to purchase the program just when you are about to remove the unwanted files.
And if you're having problems deciding if a file is legitimate or malware in FreeFixer's scan result, click on the More Info link for the file. That will open up your web browser with a page which contains additional information about the file. On that web page, check out the VirusTotal report which can be quite useful:
As a last resort, if the above steps did not solve the pop ups problem, you can block w3.css-validator.org in the Windows HOSTS file.
