How to remove HermesLookup adware from Mac computers

What is HermesLookup?

HermesLookup is a rogue application categorized as adware, which also possesses browser hijacker traits. Following successful infiltration, this app runs intrusive advertisement campaigns (i.e., delivers unwanted and harmful ads), modifies browsers and promotes fake search engines. Additionally, HermesLookup is likely to have data tracking capabilities, which are employed to monitor users' browsing activity. Due to the dubious methods used to proliferate HermesLookup, it is also classified as a Potentially Unwanted Application (PUA). One of the dubious techniques used to proliferate this application is via fake Adobe Flash Player updates. Note that bogus updaters/installers commonly distribute Trojans, ransomware and other malware.

Adware-type apps enable the placement of pop-ups, banners, coupons, surveys and other intrusive ads - typically, on any visited website. These ads significantly diminish the browsing experience, as they overlay web page content and reduce browsing speed. When clicked, intrusive advertisements redirect to sale-oriented, untrusted/rogue, compromised, deceptive/scam and malicious sites. Clicking can also trigger them to execute scripts designed to stealthily download/install rogue software (e.g. PUAs). Browser hijacker operate by reassigning the homepage, default search engine and new browser tab/window URLs to the addresses of bogus search engines. Therefore, each search query typed into the URL bar and each new browser tab/window opened redirects to the promoted address. Fake search engines are usually unable to provide unique results, and so they tend to redirect to (or cause redirection chains leading to) Yahoo, Google, Bing and other legitimate sites. Furthermore, browser hijackers can limit/deny access to the browser settings and/or reset any permitted changes made. Therefore, unless the browser hijacker is removed, recovering the affected browser is impossible. Furthermore, most PUAs (adware and browser hijackers included) track data. These unwanted apps can monitor browsing activity (URLs visited, pages viewed, search queries, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). The gathered data is often monetized by sharing it with, or selling to, third parties (potentially, cyber criminals) seeking to misuse it for profit. To summarize, the presence of PUAs on devices can lead to system infections, serious privacy issues, financial loss and even identity theft. To ensure device integrity and user safety, remove all suspicious applications and browser extensions/plug-ins without delay.

CapitalCharacterSearchPanelNotes and SimpleGuideSearch are some examples of other adware type PUAs. These apps often seem legitimate and useful, however, the advertised features are rarely operational. In fact, this is typical of all software classified as PUAs. These unwanted applications have just one purpose: to generate revenue for the developers. Regular users receive no genuine value and simply experience problems. PUAs deliver intrusive ad campaigns, force-open untrusted and malicious web pages, hijack browsers and track private information.

How did HermesLookup install on my computer?

PUAs proliferate via the download/installation set-ups of other products. This deceptive marketing method of pre-packing regular software with unwanted or malicious additions is called "bundling". Rushing through download/installation processes (e.g. ignoring terms, skipping steps and sections, etc.) increases the risk of unintentionally allowing bundled content onto systems. Note that some PUAs have "official" download pages. Once clicked, intrusive advertisements can execute scripts to download/install PUAs without users' permission.

How to avoid installation of potentially unwanted applications

You are advised to research all products before download/installation or purchase. Use only official and verified download channels. Unofficial and free file-hosting sites, P2P sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders are untrusted and should be avoided. When downloading/installing, you are advised to read the terms, explore all available options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, functions and other additions. Intrusive ads may seem legitimate and normal, however, they often redirect to dubious websites (e.g. pornography, adult-dating, gambling and others). If you encounter ads/redirects of this type, check the system and immediately eliminate all suspect applications and browser extensions/plug-ins. If your computer is already infected with HermesLookup, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
