How to remove Weather Forecast Online adware and the adverts it displays

Also Known As: Ads by Weather Forecast Online
Type: Adware
Damage level: Medium

What is Weather Forecast Online?

During a routine inspection of questionable software-promoting webpages, our researchers found the Weather Forecast Online browser extension. It is endorsed as a quick-access tool for local weather forecasts, humidity reports, and other related online content. However, our analysis revealed that this extension operates as advertising-supported software (adware) instead.

Weather Forecast Online adware overview

Adware is designed to deliver intrusive ad campaigns. In other words, it enables the placement of third-party graphical content (adverts) on visited websites and/o other interfaces.

The displayed ads promote online scams, untrustworthy/hazardous sites and software, and even malware. Some intrusive advertisements can perform stealthy downloads/installations upon being clicked.

It is pertinent to mention that any genuine products encountered through these adverts are most likely endorsed by scammers abusing their affiliate programs to obtain illegitimate commissions.

Advertising-supported software may need specific conditions to run intrusive advertisement campaigns (e.g., compatible browser/system specs or user geolocation, visits to particular websites, etc.). However, regardless of whether Weather Forecast Online delivers ads - its presence endangers device integrity and user safety.

Weather Forecast Online has data tracking functionalities. Targeted information may include: visited URLs, viewed pages, searched queries, usernames/passwords, personally identifiable details, finance-related data, etc. The gathered information can then be shared with and/or sold to third-parties (potentially, cyber criminals).

To summarize, the presence of software like Weather Forecast Online on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples

We have analyzed thousands of adware samples; Secure Text SearchParental Url BlockersOnline Document Converters, Tin Colors - are merely some of our newest finds.

Advertising-supported software usually appears legitimate and harmless. Users are enticed into download/installation with various "useful" functionalities. However, these functions seldom work as promised, and in most cases - they are utterly nonoperational.

How did Weather Forecast Online install on my computer?

We acquired Weather Forecast Online from its "official" download page. In addition to such sites, adware is endorsed on scam webpages. Most users enter these pages via redirects caused by websites using rogue advertising networks, spam browser notifications, intrusive ads, mistyped URLs, or installed adware (with browser force-opening capabilities).

Advertising-supported software can also be bundled (packed together) with regular programs. Download from untrustworthy sources (e.g., unofficial and freeware websites, P2P sharing networks, etc.) and rushed installations (e.g., used "Easy/Express" settings, etc.) increase the risk of allowing bundled content into the system.

Intrusive advertisements proliferate adware as well. When clicked on, some of these adverts can execute scripts to perform downloads/installations without user consent.

How to avoid installation of adware?

We strongly recommend researching software and downloading it from official/verified channels. When installing, it is crucial to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out of all supplementary apps, tools, extensions, etc.

We advise being cautious when browsing since fraudulent and malicious content usually appears legitimate. For example, intrusive adverts look harmless yet redirect to highly questionable sites (e.g., gambling, pornography, adult-dating, etc.).

In case of encounters with such advertisements/redirects, check the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with Weather Forecast Online, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
