Prevent being scammed by Funnymonday websites

Also Known As: Funnymonday pop-up
Type: Mac Virus
Damage level: Medium

What is "Funnymonday"?

Funnymonday is a family of websites, which operate by endorsing untrustworthy applications. This variant promotes Smart Mac Booster, which is classified as a Potentially Unwanted Application (PUA). Using scare tactics, Funnymonday urges people into downloading/installing the dubious software it advertises.

Visitors are alerted about fake threats/issues the site has supposedly detected and offers Smart Mac Booster as an app capable of eliminating these problems.

Note that no website can detect such issues. You are strongly advised against downloading/installing any applications that Funnymonday promotes - they are often bogus and nonfunctional. Web pages such as Funnymonday are generally opened by PUAs already present on the system.

Funnymonday scam

Once accessed, Funnymonday displays a pop-window. The text presented in this window states that a website visited on this day has infected the Mac Operating System with a virus. Users are urged to click "OK" to begin the 'repair process'.

After this window is closed, Funnymonday shows a different web page, which urges visitors to perform a full system scan to find and remove harmful files/applications from their MacOS. To further give the impression of legitimacy, it lists the user's device details, such as brand, OS version, browser, IP address, internet provider, and location.

Clicking the "Scan Now" button initiates a fake scan, which results in the detection of a virus called "Bankworm". Funnymonday additionally provides the title of the allegedly infected file and suggests Advanced Mac Cleaner for its removal. Following this suggestion, it redirects users to the promotional website of Smart Mac Booster.

Attempts to download this app, result in download of the maccleaner.pkg file. This file is used to spread PUAs. There are many fake Mac cleaners and optimizers online, all of which bear many similarities to Smart Mac Booster. For example, K9-MacOptimizer, Qbit Mac Optimizer, and Qbit Mac Cleaner.

Commonly, this bogus software requires activation through a purchase. Despite any payments made, any software usually remains nonoperational and the capabilities/functions they advertise do not work.

In general, PUAs are all quite similar. They often seem legitimate and lure people to install by offering "useful" and "beneficial" functions/features. These features rarely work as advertised and are often nonoperational. The only purpose of this unwanted software/content is to generate revenue for the developers.

Regular users receive no value. Browser hijackers are applications that control browsers and promote fake search engines. Adware delivers intrusive ad campaigns (pop-ups, banners, surveys, coupons, etc.). These applications also cause rogue redirects to sale-based, untrustworthy, compromised, deceptive/scam, and even malicious sites.

Some PUAs have data tracking capabilities, which they employ to monitor users' browsing habits. By monitoring browsing activity (URLs visited, pages viewed, search queries, etc.), they collect personal information (IP addresses, geolocations, and other personal details).

This data is then shared with third parties (potentially, cyber criminals) intent on misusing it for financial gain.

In summary, PUAs cause browser/system infiltration and infections, and can lead to serious privacy issues, financial loss, and even identity theft. To ensure device integrity and user safety, remove all dubious applications and browser extensions/plug-ins immediately upon detection.

The Internet is rife with scam websites. Nearly all webpages of this type share certain traits. For example, FridaylifeisWedyoulife, and Mon-thu are all similar to Funnymonday. They operate by promoting various products, typically using scare tactics.

They show alerts/alarms of 'detected viruses', malware, unwanted apps and other threats/issues. Most users access these sites via redirects generated by intrusive ads or PUAs.

How did potentially unwanted applications install on my computer?

Some PUAs have "official" download websites (e.g. Smart Mac Booster), however, they also proliferate through the download/install set-ups of other software. This false marketing tactic of pre-packing regular content with PUAs is called "bundling".

By rushing though download/installation processes (ignoring terms, skipping steps, etc.), many users endanger devices with potential infiltration and infections. Once clicked, intrusive ads can execute scripts to download/install unwanted applications, without users' consent.

How to avoid installation of potentially unwanted applications

Research software/content to verify its legitimacy, before downloading/installing. Use only official and verified download sources should. P2P sharing networks (BitTorrent, Gnutella, eMule, etc.), free file-hosting sites, third party downloaders and similar channels are untrustworthy and should not be used. Download/Installation processes should be approached with caution.

Read the terms, study all available options, use the "Custom/Advanced" settings, and decline download/installation of additional apps, tools, features, etc. Intrusive advertisements may seem legitimate and innocuous, however, they often redirect to dubious web pages (e.g. gambling, pornography, adult-dating, etc.).

If you experience ads/redirects of this type, inspect the device and remove all suspect applications and/or browser extensions/plug-ins without delay. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.

Cybercriminals strive to create their rogue pop-up windows to look trustworthy, however, scams typically have the following characteristics:

  • Spelling mistakes and non-professional images - Closely inspect the information displayed in a pop-up. Spelling mistakes and unprofessional images could be a sign of a scam.
  • Sense of urgency - Countdown timer with a couple of minutes on it, asking you to enter your personal information or subscribe to some online service.
  • Statements that you won something - If you haven't participated in a lottery, online competition, etc., and you see a pop-up window stating that you won.
  • Computer or mobile device scan - A pop-up window that scans your device and informs of detected issues - is undoubtedly a scam; webpages cannot perform such actions.
  • Exclusivity - Pop-up windows stating that only you are given secret access to a financial scheme that can quickly make you rich.

How do pop-up scams work?

Cybercriminals and deceptive marketers usually use various advertising networks, search engine poisoning techniques, and shady websites to generate traffic to their pop-ups. Users land on their online lures after clicking on fake download buttons, using a torrent website, or simply clicking on an Internet search engine result.

Based on users' location and device information, they are presented with a scam pop-up. Lures presented in such pop-ups range from get-rich-quick schemes to fake virus scans.

How to remove fake pop-ups?

In most cases, pop-up scams do not infect users' devices with malware. If you encountered a scam pop-up, simply closing it should be enough. In some cases scam, pop-ups may be hard to close; in such cases - close your Internet browser and restart it.

In extremely rare cases, you might need to reset your Internet browser. For this, use our instructions explaining how to reset Internet browser settings.

How to prevent fake pop-ups?

To prevent seeing pop-up scams, you should visit only reputable websites. Torrent, Crack, free online movie streaming, YouTube video download, and other websites of similar reputation commonly redirect Internet users to pop-up scams.

To minimize the risk of encountering pop-up scams, you should keep your Internet browsers up-to-date and use reputable anti-malware application. For this purpose, we recommend Combo Cleaner Antivirus for macOS.

What to do if you fell for a pop-up scam?

This depends on the type of scam that you fell for. Most commonly, pop-up scams try to trick users into sending money, giving away personal information, or giving access to one's device.

  • If you sent money to scammers: You should contact your financial institution and explain that you were scammed. If informed promptly, there's a chance to get your money back.
  • If you gave away your personal information: You should change your passwords and enable two-factor authentication in all online services that you use. Visit Federal Trade Commission to report identity theft and get personalized recovery steps.
  • If you let scammers connect to your device: You should scan your computer with reputable anti-malware (we recommend Combo Cleaner Antivirus for macOS) - cyber criminals could have planted trojans, keyloggers, and other malware, don't use your computer until removing possible threats.
  • Help other Internet users: report Internet scams to Federal Trade Commission.
