How to remove "Sundayfunny" from Mac computers

What is "Sundayfunny"?

Sundayfunny is a family of scam web sites designed to promote untrustworthy applications. This variant advertises Smart Mac Booster, which is classified as a Potentially Unwanted Application (PUA). Websites of this type operate using scare tactics to trick visitors into downloading/installing the software that they endorse. Sundayfunny alerts users of viruses it has supposedly detected and offers Smart Mac Booster to eliminate them. Note that no website is capable of finding issues/threats on devices and the alarms they display are fake. Furthermore, applications promoted on these web pages tend to be bogus and nonoperational. Few visitors access these sites intentionally, and most are redirected by PUAs already present on the system.

Sundayfunny scam

Sundayfunny first displays a pop-up window with a message stating that a website the user supposedly visited earlier has infected the device with a virus. To begin the repair process, the user is urged to press "OK". Once the pop-up is closed, another web page is shown, the contents of which elaborate more on the supposed threat. It repeats the origin of the virus and informs visitors that a full system scan is necessary to locate harmful files/applications and remove them. The site also lists device information (brand, OS version, browser, IP address, Internet provider and location) to further give the impression of legitimacy. Following the instructions, Sundayfunny initiates a fake system scan. This results in "detection" of the "Bankworm" virus, which is listed as high-risk. Additionally, it names the allegedly infected file. The Advanced Mac Cleaner is promoted for the removal of "Bankworm" - the application is free and apparently has a high rating. In fact, clicking the "REMOVE VIRUS NOW" button redirects users to the promotional site of Smart Mac Booster. The download process of this software leads to download of the maccleaner.pkg file, which is known for the proliferation of PUAs. Typically, this software requires activation to become functional (i.e., it must be purchased to perform the promised functions). Despite any purchase, however, these applications remain nonoperational. There are many PUAs similar to Smart Mac Booster online, including, for example, MacCleansePro, K9-MacOptimizer, and Mac Clean Pro. You are advised against downloading/installing the maccleaner.pkg file and the aforementioned app.

Most PUAs share certain common traits. They often seem legitimate, and show little difference to genuine applications this type. Users are enticed to install them, however, their features are rarely operational or do not work as advertised. The only purpose of all unwanted content is to generate revenue for the developers, whilst regular users receive no value. PUAs have various dangerous capabilities. They can cause redirects to sale-based, untrustworthy, compromised, deceptive/scam and even malicious websites. Some hijack browsers and promote fake search engines. Others run intrusive advertisement campaigns (pop-ups, banners, surveys, coupons, etc.), which severely diminish the browsing experience and carry certain risks. PUAs possess data tracking capabilities. They monitor users' browsing activity (browsing and search engine histories) and collect personal information (IP addresses, geolocations, and other details). This private data is then shared with third parties and can end up being used for criminal purposes. In summary, unwanted apps can cause browser and system infiltration/infections, and lead to serious privacy issues, financial loss, and even identity theft. To ensure device and user safety, remove all suspicious applications and browser extensions immediately upon detection.

FirdayfunWenfuntoday, and Funnytues are just some examples of scam website families identical to Sundayfunny. Deceptive web pages of this kind employ scare tactics to encourage users into downloading, installing, and purchasing the software they endorse. The content they advertise is mostly bogus and nonfunctional. These sites are commonly accessed via redirects generated by intrusive advertisements or by PUAs.

How did potentially unwanted applications install on my computer?

PUAs often proliferate through the download/installation set-ups of other software. This deceptive marketing tactic of pre-packing regular product with unwanted or malicious applications is called "bundling". The risk of allowing such content onto systems increases due to rushing download/installation processes (e.g. ignoring terms, skipping steps, using pre-set options, etc.). Some unwanted apps have "official" download web pages. Intrusive advertisements do not need user consent to download/install PUAs. Once clicked, they can execute scripts, designed for this purpose.

How to avoid installation of potentially unwanted applications

Research content, before downloading/installing. Use only trustworthy and verified download channels. Do not use P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting websites, third party downloaders and similar sources - they are classed as untrustworthy. When downloading/installing, read terms, explore all available options, use the "Custom/Advanced" settings and decline additional apps, tools, features, etc. Intrusive advertisements typically seem normal and harmless, however, they redirect to dubious sites (e.g. gambling, pornography, adult-dating and others). If you encounter these ads/redirects, 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.
