What is "Zxcvc"?
Zxcvc is a family of scam sites, designed to endorse untrustworthy applications. This variant promotes the Smart Mac Booster app and operates by warning users of a virus, which it has allegedly detected. It offers specific software for its removal. Note that no website can find threats or issues present on their devices.
These claims are false and should not be trusted. Deceptive web pages that advertise these apps are bogus and the software is nonfunctional.
Therefore, you are strongly advised against installation of these apps. Most visitors to Zxcvc sites access them unintentionally, since they are redirected by Potentially Unwanted Applications (PUAs) already present on their Mac Operating Systems.
Visitors to Zxcvc first see a pop-up window. The message within it claims that a website visited earlier has infected the MacOS with a virus. Users are encouraged to click "OK" to initiate the repair process. After this window is closed, Zxcvc shows a different page.
It repeats the initial claim and urges visitors to perform a full system scan to locate and eliminate harmful files/applications. To further give the impression of legitimacy, this site also lists device details (brand, OS version, browser, IP address, Internet provider and location).
Following the instructions issued by Zxcvc will start a fake scan, which detects a virus called "Bankworm". Zxcvc then recommends the Advanced Mac Cleaner application for removal of this threat. Once the "REMOVE VIRUS NOW" button is clicked, users are redirected to the promotional web page of Smart Mac Booster.
This leads to download of the maccleaner.pkg file, which is typically used to proliferate PUAs. There are many untrustworthy and rogue apps similar to Smart Mac Booster, and they are spread in the same way. Examples include MacCleansePro, K9-MacOptimizer, Qbit Mac Optimizer, and many others.
This software usually requires activation to become operational, however, even after purchase, it remains nonoperational. You are strongly advised against installing maccleaner.pkg or Smart Mac Booster.
PUAs share many similarities. They often seem legitimate and tempt users into downloading/installing them with offers of various "useful" features. Regardless of how good these promises may sound, the advertised functions are rarely operational (even after activation).
The only purpose of unwanted apps is to generate revenue for the developers, whilst regular users receive no value. PUAs force-open sale-based, untrustworthy, compromised, deceptive/scam and malicious web pages. They can also run intrusive advertisement campaigns, which deliver ads that diminish the browsing experience and carry certain risks.
Other types make unauthorized changes to browsers (hijack them) and promote fake search engines. Frequently, PUAs also possess data tracking capabilities. By monitoring users' browsing habits (search engine and browsing histories), they collect personal information (IP addresses, geolocations and other details).
This sensitive data is then shared with third parties and can end up being used for criminal purposes. To summarize, PUAs can cause browser and system infiltration and infections, and lead to financial loss, serious privacy issues and even identity theft. To ensure device and user safety, remove all dubious applications and browser extensions/plug-ins immediately.

Vnbue, Badmonday, and Sundayfunny are a few examples of scam website families identical to Zxcvc. Deceptive sites usually employ scare tactics to tempt visitors into downloading/installing and purchasing dubious software.
Therefore, these web pages display warnings/alerts/alarms of "detected" threats and issues, and then offer applications for the removal of these bogus problems. Most of the promoted apps are fake and nonfunctional. Visitors generally arrive at Zxcvc and similar sites through redirects generated by PUAs or intrusive advertisements.
How did potentially unwanted applications install on my computer?
Some PUAs (including Smart Mac Booster) have official download websites, however, they can also be downloaded/installed together with other software. This deceptive marketing method of pre-packing regular content with unwanted apps is called "bundling".
By rushing though download/installation set-ups (e.g. ignoring terms, skipping steps, etc.), many users risk inadvertently allowing bundled software onto their devices. Once clicked, intrusive advertisements can execute scripts to download/install PUAs without users' consent.
How to avoid installation of potentially unwanted applications
Research content carefully before downloading/installing. Use only official and verified download channels. Avoid P2P sharing networks (BitTorrent, Gnutella, eMule, etc.), free file-hosting sites, third party downloaders and similar sources, as they are untrusted. Approach download/Installation processes with caution.
Read the terms, explore all possible options, use the "Custom/Advanced" settings, and opt-out of supplementary apps, tools, functions, etc. Intrusive ads often seem legitimate and harmless, however, they can redirect to dubious web pages (e.g. gambling, pornography, adult-dating and others).
If you encounter advertisements/redirects of this type, inspect 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.

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.
