Yes, they are. Initially, they can look safe – just a colourful window that appears from time to time. However, the contents of this window differ drastically from what you used to see in pop-ups. Fast-scan.net site is controlled by fraudsters, who deliberately show hundreds and thousands of irrelevant ads in pop-ups. They also don’t follow any common sense and can make sporadic pop-ups into a hurricane of promotions. For weak systems, that may be enough to cause performance issues.

Even though hackers make the ads looking similar to ones from Amazon, Walmart or Ebay, the website these ads will throw you to are completely different. And these pages may offer you to turn on other pop-ups, install a “useful” program, or pay for a thing at a big discount and never receive it. Let’s leave aside the cases when pop-up notifications promote phishing pages or straightforward malware. There’s no way these pages will bring you any good, thus interacting with them is a very bad idea.

# lines or following the machine name denoted by a '#' symbol.
