How to remove ArchimedesLookup adware from Mac?

What is ArchimedesLookup?

ArchimedesLookup is a rogue application, categorized as adware and it possesses browser hijacker traits. It operates by running intrusive advertisement campaigns, making modifications to browser settings and promoting fake search engines. Most adware and browser hijackers gather browsing-related information, and it is highly likely that ArchimedesLookup also has such data tracking abilities. Due to the dubious methods used to distribute this app, it is deemed to be a PUA (Potentially Unwanted Application). Once of the distribution techniques used for ArchimedesLookup is via fake Adobe Flash Player updates. It is noteworthy that illegitimate software updaters/installers proliferate not only PUAs but malware (e.g. ransomware, trojans, etc.) as well.

ArchimedesLookup adware distributed via illegitimate Flash Player updater/installer

Adware delivers pop-ups, banners, coupons, surveys and other intrusive advertisements; typically, by enabling their placement on any visited website. These ads slow down the browsing speed and overlay page content. Upon being clicked, they redirect to various untrustworthy/malicious websites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers assign the addresses fake web searchers as browsers' homepage, default search engine and new tab/window URLs. Hence, every single search query typed into the URL bar and new browser tab/window opened - redirect to the promoted address. Illegitimate search engines are rarely capable of providing search results, so they redirect to Google, Yahoo, Bing and other genuine ones. Browser hijackers can reassign any changes users attempt to make for their browsers and/or deny access to the browser's settings. Therefore, recovering a hijacked browser is impossible without removing the software affecting it. Most PUAs (adware and browser hijackers included) can track data. They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather personal information extracted from it (IP addresses, geolocations and other details). This sensitive data is usually shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of unwanted apps on devices can lead to system infections, financial losses, serious privacy issues and even identity theft. To protect device and user safety - all suspect applications and browser extensions/plug-ins must be eliminated without delay.

EngageSearchBinarySignSearchDynamicAnalog are a couple examples of other adwares. This software look ordinary and offers a wide variety of "handy" functionalities. However, the promised features are seldom operational and this is typical of all PUAs. The only goal of unwanted applications is to generate profit for the developers; to users - it has no real value and can instead cause various issues. PUAs are designed to deliver intrusive advert campaigns, cause redirects, modify browsers and collect vulnerable information.

How did ArchimedesLookup install on my computer?

PUAs are distributed through download/installation setups of other products. This false marketing technique of pre-packing regular software with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g. ignored terms, skipped steps and sections, etc.) increase the risk of unintentionally allowing dubious and/or bundled content into the system. Select PUAs have "official" download pages. Intrusive ads proliferate these applications as well. Once clicked on, they can execute scripts to download/install PUAs without user permission.

How to avoid installation of potentially unwanted applications?

It is recommended to research software before download/installation. All downloads must be done from official and verified sources. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer deceptive and/or bundled content, due to this these download channels are deemed to be untrustworthy. When downloading/installing, it is important to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, features, and so on. Intrusive adverts look legitimate and harmless, however they redirect to questionable webpages (e.g. gambling, pornography, adult-dating, etc.). Should users experience advertisements/redirects of this kind, they must inspect the system and immediately remove all suspicious applications and/or browser extensions/plug-ins from it. If your computer is already infected with ArchimedesLookup, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
