How to remove "Wenfuntoday" from Mac computers

What is "Wenfuntoday"?

Wenfuntoday is a family of scam websites designed to promote untrustworthy applications. This variant endorses the Smart Mac Booster app, a rogue product classified as a Potentially Unwanted Application (PUA). Scam websites operate by employing various scare tactics to trick visitors into downloading/installing the software they advertise. Essentially, Wenfuntoday displays alerts informing users that their MacOS (Mac Operating System) is infected. It offers Smart Mac Booster as an application capable of eliminating these threats. Note that no website can detect threats/issues on devices. Therefore any viruses/malware that these web pages claim to detect are fake. Furthermore, software promoted on these sites is often bogus and nonoperational. Typically, sites such as Wenfuntoday are opened by PUAs already present on the system.

Wenfuntoday scam

Wenfuntoday first displays a pop-up window. The message in this window informs users that a website they visited earlier in the day has infected their MacOS with a virus. They are urged to click "OK" to begin the repair process. Closing the pop-up shows a different web page, which repeats the alert and states that a full system scan is required to find and delete harmful files/applications from the device. To further give the impression of legitimacy, it also lists the device details (brand, OS version, browser, IP address, internet provider, and location). The "Scan Now" button starts a fake scan. This scan "detects" a virus called "Bankworm". It also provides the location of the "infected" file. The software suggested for removal of the virus is Advanced Mac Cleaner. When the "REMOVE VIRUS NOW" is clicked, however, users are redirected to the promotional site of Smart Mac Booster. During the download process of this application, the maccleaner.pkg file is downloaded. The file is known to be used for PUA proliferation. There are dozens of fake apps similar to Smart Mac Booster including, for example, K9-MacOptimizerQbit Mac Optimizer, and Advanced Mac Booster. This fake software typically requires activation (i.e. must be purchased to become active/operational). Despite any payments made, these applications remain nonoperational.

Unwanted apps share many similarities. They often seem legitimate and tempt users to install by offering a wide variety of "useful" features. These features rarely work as advertised and are usually nonfunctional. The only purpose of unwanted software/content is to generate revenue for the developers. Regular users receive no value. PUAs can function as browser hijackers, control browsers, and promote fake search engines. Adware-type PUAs run intrusive advertisement campaigns. The ads they deliver (pop-ups, banners, surveys, etc.) significantly diminish the browsing experience and carry certain risks. Unwanted applications also cause redirects to untrustworthy, deceptive and even malicious web pages. PUAs often have data tracking capabilities. They record browsing activity (browsing and search engine histories) and gather users' personal information (IP addresses, geolocations, and other details). This sensitive data is then shared with third parties (potentially, cyber criminals) intent on misusing it for financial gain. To summarize, PUAs can cause browser and system infiltration/infections, and lead to serious privacy issues and even identity theft. To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins immediately.

Scam web pages are very common across the internet. Most have similar traits. For example, FridaylifeisMondaysunday, and Mon-thu are all akin to Wenfuntoday. Frequently, these sites promote fake software by warning users of viruses, malware, and other so-called threats and detected issues. Most visitors to these websites enter them inadvertently via redirects caused by intrusive ads or PUAs.

How did potentially unwanted applications install on my computer?

Some PUAs, including Smart Mac Booster, have "official" websites on which they are endorsed as "free" software. These rogue applications can also be downloaded/installed together with other programs. This deceptive marketing method of pre-packing ordinary software with unwanted content is called "bundling". Rushing download/installation processes (ignoring terms, skipping steps, etc.) increases the risk of system infiltration and infection. Intrusive ads also spread PUAs. Once clicked, they can execute scripts to stealthily download/install them.

How to avoid installation of potentially unwanted applications

Research all content before downloading/installing. Use only trustworthy and verified download channels. P2P sharing networks (BitTorrent, Gnutella, eMule, etc.), unofficial and free file-hosting sites, third party downloaders, and similar sources are untrusted and should not be used. Treat download/Installation processes with caution. Read the terms, explore all options, use the "Custom/Advanced" settings, and opt-out of downloading/installing supplementary apps, tools, features, etc. Intrusive ads usually seem legitimate and harmless, however, they often redirect to dubious web pages (e.g. gambling, pornography, adult-dating, and others). If you experience ads/redirects of this kind, check the system and remove all dubious 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.
