What is centerplaceofupgrade[.]pro?

centerplaceofupgrade[.]pro is a deceptive site promoting a fake Adobe Flash Player updater scam. The web page claims that the plug-in is outdated and recommends installation of the latest updates. Note that bogus software updates are typically used to proliferate nonoperational, untrustworthy and malicious content.

I.e., they can spread various Potentially Unwanted Applications (PUAs) such as adware and browser hijackers, and even malware (e.g. ransomware, trojans, etc.). Few people visit scam pages intentionally - most are redirected by intrusive ads or PUAs already installed on the system.

centerplaceofupgrade[.]pro scam

There are several, practically identical scam variants run on centerplaceofupgrade[.]pro. Visitors first see several pop-up windows that appear in quick succession. Most contain an identical message: Adobe Flash Player is out of date and requires updating.

The messages are phrased slightly differently. The large pop-up in the middle of the page goes into more detail. Following claims about Flash being outdated, it informs users that this plug-in is an essential piece of software. Flash Player enables online media such as audio, video, animation and games.

Supposedly, the current version on visitors' systems is lacking the latest security updates, and has therefore been blocked. To continue using it, the scam recommends installation of the latest updates. If any of the "Download/Install/Update" buttons are clicked, the fake updates are downloaded and the page provides the installation instructions.

The pop-up instructs users to find the downloaded file in within their downloads list, and then to double-click it and confirm installation by clicking "Continue and Install". Note that trusting centerplaceofupgrade[.]pro and following the instructions will not update Adobe Flash Player - instead, users will allow untrustworthy/malicious software onto their devices.

This can lead to serious issues, endanger system integrity and users' safety. You are strongly advised against trusting this scam and others similar to it. To avoid downloading/installing bogus and potentially harmful content, all downloads should be performed from official and verified sources.

Software should likewise be updated using functions/tools provided by legitimate developers.

As mentioned, deceptive/scam sites are commonly accessed via redirects caused by PUAs, however, these apps can also force-open sale-oriented, untrustworthy, rogue, compromised and malicious web pages. This is not the only capability of these unwanted applications.

They can run intrusive advertisement campaigns, delivering dangerous ads that diminish the browsing experience. When clicked, they can redirect to similarly dubious/malicious pages and stealthily download/install unwanted content (e.g. PUAs). Other PUAs can modify browsers and limit/deny access to settings.

These apps often have data tracking capabilities, which are employed to monitor and gather browsing-related information. Data of interest includes (but is not limited to) browsing and search engine histories, IP address, geolocation and users' personal details.

This vulnerable information can then be shared with third parties, seeking to misuse it for profit. To summarize, the presence of PUAs on systems can lead to browser/system infiltration and infections, serious privacy issues, financial loss and even identity theft. Therefore, all suspicious applications and browser extensions/plug-ins must be removed immediately upon detection.

centersourceoffreeupgrades.besttheworldofcontents.info, and startmostnewestprogram.icu are examples of other scams similar to centerplaceofupgrade[.]pro.

There are various models employed to trick users into performing specific actions (e.g. downloading/installing/purchasing untrustworthy and/or malicious content, revealing their personal information, making monetary transactions, calling expensive numbers, etc.).

Through warnings of "outdated/missing" software or infections "detected" on the system, prize announcements, "amazing" offers and similar, the schemes generate profit for their designers. There are thousands of deceptive websites on the web, and you are thus urged to be very cautious when browsing.

How did potentially unwanted applications install on my computer?

Fake updaters are just one way in which PUAs can infiltrate systems. They can also be downloaded/installed together with other products. The deceptive marketing technique of pre-packing regular content with unwanted or malicious software is called "bundling".

While opting-out of these unwanted additions is often possible, rushing download/installation processes (e.g. skipping steps and sections, using pre-set options, etc.) increases the risk of unintentionally allowing bundled content onto devices. Note that some PUAs have "official" download web pages.

Intrusive ads also proliferate PUAs. Once clicked, they can execute scripts to download/install these rogue apps without users' consent.

How to avoid installation of potentially unwanted applications

All products should be researched carefully prior to download/installation or purchase. Use only official and verified download channels channels, as opposed to free file-hosting sites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), third party downloaders or other untrustworthy sources.

When downloading/installing, read the terms, explore all available options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features and so on. Intrusive advertisements usually seem legitimate and harmless, however, they can redirect to highly dubious web pages (e.g. gambling, pornography, adult-dating and others).

If you encounter these ads/redirects, inspect the system 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.
