How to remove LogicalUpdate adware from Mac?

What is LogicalUpdate?

LogicalUpdate is a piece of rogue software, classified as adware. Additionally, this application has browser hijacker qualities. Following successful infiltration, it runs intrusive advert campaigns and makes changes to browser settings - in order to promote fake search engine. LogicalUpdate promotes z6airr.com on Safari browsers and search.productivebrowser.com on Google Chrome browsers. Due to the questionable techniques used to distribute this app, it is also deemed to be a PUA (Potentially Unwanted Application). Most PUAs have data tracking abilities, employed to spy on users' browsing habits.

LogicalUpdate adware

Adware enables the placement of pop-ups, banners, surveys, coupons and other intrusive adverts - typically, on any visited site. The delivered ads severely diminish the browsing experience, as they overlay webpage content and slow down the browsing speed. Furthermore, once clicked on, intrusive advertisements redirect to various unreliable/malicious websites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers assign the addresses of fake web searchers as browsers' homepage, default search engine and new tab/window URLs. Hence, with such a piece of software installed: every new browser tab/window opened and web search done via the URL bar - redirect to the promoted address. LogicalUpdate also makes the aforementioned modifications to browsers and causes the same redirects; on Safari it redirects to z6airr.com and on Google Chrome - search.productivebrowser.com. Illegitimate search engines are seldom capable of providing search results, so they tend to redirect to Google, Yahoo, Bing and other genuine ones. Browser hijackers can also restrict/deny access to the browser's settings and/or undo any permitted changes made, thereby ensuring persistence. What is more, most PUAs (adware and browser hijackers included) have data tracking abilities. They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). This vulnerable data is then shared with and/or sold to third parties (potentially, cyber criminals), likewise intent on misusing it for financial gain. In summary, presence of unwanted software on devices can lead to system infections, serious privacy issues, financial losses and even identity theft. To protect device and user safety, all dubious applications and browser extensions/plug-ins must be removed without delay.

RecordEnumeratorOperativeProgram and LeadingOperation are couple examples of other adware-type applications. They appear legitimate and harmless. Users are lured into download/installation and/or purchase with offers of various "useful" functionalities. However, the promised features are usually nonoperational. This applies to practically all PUAs. The sole purpose of unwanted software is to generate revenue for the developers; to users - it has no real value and can instead cause severe problems. PUAs operate by delivering intrusive ad campaigns, modifying browsers, causing redirects, collecting sensitive and personally identifiable information.

How did LogicalUpdate install on my computer?

PUAs can be downloaded/installed together with other products. This deceptive marketing method of packing ordinary software with unwanted or malicious additions - is called "bundling". By rushing through download/installation processes (e.g. by skipping steps and sections, using "Easy/Express" settings, etc.) - users risk unintentionally allowing bundled content into their devices. Intrusive adverts can infiltrate PUAs into systems as well. Upon being clicked, the ads can execute scripts to download/install these applications without user consent. Select PUAs have "official" promotional webpages, from which they can be downloaded.

How to avoid installation of potentially unwanted applications?

It is strongly recommended to research software before download/installation and/or purchase. All downloads must be done from official and verified sources. Since untrustworthy download channels, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content. When downloading/installing, it is advised to read terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out from additional apps, tools, features, etc. Intrusive advertisements appear legitimate, however they redirect to highly questionable sites (e.g. gambling, pornography, adult-dating, and so on). Should users encounter ads and/or redirects of this kind, they must check their devices and immediately remove all suspicious applications and browser extensions/plug-ins detected. If your computer is already infected with LogicalUpdate, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
