How to remove redirects to theworldofcontents[.]info from Mac?

What is theworldofcontents[.]info?

Theworldofcontents[.]info is a scam webpage, pushing a fake Flash Player updater. There are several variants of this scam's design/appearance, though the purpose is much the same. The site claims that visitors' Flash Player may be outdated and recommends them to update it. Illegitimate updaters are used to spread a variety of untrustworthy and malicious content. For example, they are employed to proliferate PUAs (Potentially Unwanted Applications) and even malware (e.g. trojans, ransomware, etc.). Few users access websites like theworldofcontents[.]info intentionally, most get redirected by intrusive advertisements or by PUAs, already installed onto the system.

theworldofcontents[.]info scam

When entered, both variants of theworldofcontents[.]info display multiple pop-up windows. The initially displayed, center pop-up states that Flash Player is an essential browser plug-in. It enables users to play video, animation and audio media, as well as games - online. As Flash might be lacking latest security updates (i.e. is outdated) - it is possible that the plug-in has been blocked. To continue using Flash Player, the scam urges visitors to update it. The window at the bottom-right instructs users to install the newest updates for improved performance. This scam version presents another pop-up, which overlays the one shown in the center of the page. It repeats the same message - Flash may be out-of-date and lacking security updates, thereby it might not work. Each of these windows have "Download/Update" buttons, clicking on any - leads to the download of the illegitimate updates. The other variant of this scheme, displays two pop-ups. The window at the top-right corner, informs users that they need to download an updated new version of said plug-in. The one in the middle of the webpage presents visitors with a loading bar, which allegedly represents the download process of the Flash updates. Installing them will only take a few seconds and require no restart/reboot. This pop-up also has buttons to download the fake updater. Once the download process has begun, theworldofcontents[.]info provides users with instructions how to install the updates. However, following the steps will allow untrustworthy/malicious software onto the device, instead of updating Flash Player. Content promoted via such dubious methods is highly likely to lead to serious issues; therefore, it is strongly advised against downloading/installing it.

Deceptive websites are commonly force-opened by PUAs, yet they can redirect to other sale-based, untrustworthy/rogue, compromised and malicious pages as well as. However, they can have different abilities. Some unwanted apps run intrusive advertisement campaigns, i.e. deliver browsing-quality diminishing and harmful ads. As mentioned in the introduction, intrusive adverts also redirect to various questionable webpages and can stealthily download/install content - when they are clicked. Other types of PUA can make unauthorized changes to browsers and limit/deny access to their settings. Most PUAs, regardless of their other functions, can track data. They monitor users' browsing habits (URLs visited, search queries typed, etc.) and collect their personal information (IP addresses, geolocations and real-life details). This vulnerable data can then be shared with third parties, intent on misusing it for profit. To summarize, PUAs can not only cause browser and system infiltrations/infections, but also result in financial losses, severe privacy issues and even identity theft. To protect device integrity and user safety, all suspect applications and browser extensions/plug-ins must be removed without delay.

Mainplaceupgradesfree.infostartmostnewestprogram.icufineplaceupgradefree.info are a few examples of scam sites, promoting fake software updaters. Deceptive pages use social engineering and scare-tactics to trick users into downloading/installing and/or purchasing unreliable/malicious content, revealing personal details (e.g. banking account or credit card credentials), making monetary transactions (e.g. payment for "services rendered", various fees) and so on. The sole goal of these scams is to generate revenue for their designers at the expense of users.

How did potentially unwanted applications install on my computer?

PUAs can infiltrate devices under the guise of other software (e.g. fake updaters). However, they can also be downloaded/installed together with regular products. This false marketing method of pre-packing ordinary programs with unwanted (or malicious) content is called "bundling". Rushed download/installation processes (e.g. ignored terms, used pre-set options, etc.) - endangers systems with potential infiltrations and infections. Some apps of this kind have "official" download pages, which are typically pushed by deceptive/scam websites. When an intrusive ad is clicked, it can execute scripts, designed to download/install PUAs without user consent.

How to avoid installation of potentially unwanted applications?

It is advised to research content, before downloading/installing it. Users are encouraged to only use official and verified download channels. Untrustworthy download sources, e.g. P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting sites and other third party downloaders - can offer deceptive and/or bundled software. All updates should be done with tools/functions provided by genuine developers; third party updaters are deemed to be high-risk, so they are expressly advised against use. When downloading/installing, it is recommended to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features and so on. Intrusive advertisements often appear legitimate and harmless, however they redirect to dubious webpages (e.g. pornography, adult-dating, gambling and others). Should users encounter ads/redirects of this type, it is necessary to check the system and immediately remove all suspicious applications and/or browser extensions/plug-ins from it. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
