The Weather Forecast Online is a browser extension promising to provide users with relevant weather information, such as local forecasts, humidity, reports and other useful content. Unfortunately, when installed, the application quickly reveals that it also carries significant adware capabilities. As a result, users are likely to be subjected to an influx of unwanted advertisements promoting questionable software products and websites (technical support tactics, fake giveaways, phishing schemes, etc.).

Adware applications typically hide their primary functionality, but, in many cases, the applications themselves are hidden from the user's attention through the use of dubious distribution tactics - software bundles, fake installers/updates and more. That is why these applications often fall in the PUP (Potentially Unwanted Programs) category as well.

Users should be warned that most PUPs are equipped with additional functions that they carry out silently in the background of the system. Most frequently, these functions involve data monitoring and exfiltration. The intrusive applications will monitor the users' browsing activities, collect device details, or even try to obtain account credentials, banking data, payment information, and credit/debit card numbers from browsers' autofill data. The harvested information is packaged and transmitted to a server under the control of the PUP's operators.
