You open your web browser, click on a link and suddenly you get a pop up that looks something like one of these:
DO NOT CALL any of these numbers! This is an adware scam. Adware is a type of malware that is used to describe software which presents unwanted advertisements to the user of a computer. The advertisements produced by adware are sometimes in the form of a pop-up or sometimes in an "unclosable window."
You will need to fully stop the browser process and try to remove the adware. You can open a private browsing window and clear your cache and history. You can also try using Malwarebytes AdwCleaner to remove the adware. It is a free download, and be warned - it may require your computer to be restarted.
Or contact BSCANS for help in removing the adware.
