I erased a program that I had in my computer, I don't know how come, named Yellow adblocker. But the box is still here and words with different colors that have links to repair programs or google. Under the box I have the option of closing the box and the box disappears. But how strange! When I go to the page of mini adblocker they tell that we can dis-installed the program looking for mini adblocker. But this program is not in my list of programs.
Make sure you don't download anything that's recommended by one of these advertisements--they're probably malware or a virus or something. I'd also recommend not logging into any banking or financial websites on your computer until you get it fixed, and probably not logging into any email accounts you have.
I'd try the link Palinurus suggested first and see if that fixes it.
It's possible that it's also caused by a nefarious extension or add on to your web browser. If you installed a new extension in your web browser (this is more likely in Chrome, but possible in Firefox, maybe other browsers) recently, then I'd suggest uninstalling it and see if that fixes it. It might be worth getting rid of all your extensions in your web browser if it doesn't fix it. If that doesn't work either, try switching to another web browser on your computer and see if the ads are still there--if they are, then there's a virus/malware installed in your operating system (as opposed to just your web browser--bigger problem).
The link that Palinurus sent may fix that, but if that's the case, I'd ultimately suggest reinstalling your operating system to be on the safe side--the reason being that malware has become quite sophisticated over the years and will steal your personal information (banking, identity, logins to websites, etc), which can cause serious problems in your life, and you can't be certain that it's been totally removed. The only thing pretty much guaranteed to get rid of it (not 100%, but generally close enough) is to reinstall your operating system. Your computer might have a "factory restore" option--that'll be the easiest route to take to accomplish that. This will result in your settings and possibly data being deleted, so you may want to backup your personal data first. Make sure to have antivirus software installed on your computer before attempting to restore the data, in case the virus also infects the backup, to avoid re-infecting yourself.
If you really don't know what you're doing and don't want to lose data on your computer, then I'd recommend finding someone who can repair/restore it.
