How to remove WebAdvancedSearch adware from Mac?

What is WebAdvancedSearch adware?

WebAdvancedSearch is an adware-type application that had browser hijacker traits. It is designed to deliver intrusive advertisement campaigns and modify browsers in order to promote fake search engines. Most adware-types and browser hijackers have data tracking abilities, which are used to spy on users' browsing activity - and it is very likely that WebAdvancedSearch has such functionalities as well. Due to WebAdvancedSearch's questionable distribution techniques, it is considered to be a PUA (Potentially Unwanted Application). This app has been observed being proliferated via fake Adobe Flash Player updates. It is noteworthy that illegitimate software updaters/installers are also used to spread malware (e.g. trojans, ransomware, cryptominers, etc.).

Adware operates by enabling placement of pop-ups, banners, surveys, coupons and other intrusive ads - typically, on any visited website. These adverts limit website visibility and browsing speed, thereby seriously diminishing the browsing quality. However, intrusive advertisements are more than just an annoyance - they are deemed to be harmful as well. When clicked on, the adverts redirect to sale-oriented, untrustworthy, rogue, deceptive/scam, compromised and malicious websites. Additionally, some intrusive ads can stealthily download/install software (e.g. PUAs) - upon being clicked. Browser hijackers assign the addresses of illegitimate web searchers as browsers' homepage, default search engine and new tab/window URLs. Hence, new browser tabs/windows opened and every single search query typed into the URL bar - redirect to the promoted address. Fake search engines have no genuine value to users, as they are rarely capable of providing search results - so, they redirect to Yahoo, Google, Bing or other genuine ones. Furthermore, recovering a hijacked browser without removing the software affecting it - is impossible. Since any changes users attempt to make to their browsers can be automatically reset, if access to the browser's settings is permitted at all. What is more, most PUAs (adware and browser hijackers included) can track data. They can record users' browsing habits (URLs visited, pages viewed, search queries typed, etc.) and collect personal information (IP addresses, geolocations and other details). The gathered 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, severe 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.

ExtendedTaskAdvancedProcesserAdjustableValue and PlusAbout are some examples of other adware-type apps. They tend to look legitimate and handy. Users are lured into download/installation with a wide variety of "useful" functionalities. However, despite how good the promised features may sound - they are seldom operational. In fact, this applies to practically all PUAs. The sole purpose of unwanted applications is to generate revenue for the developers; to users - it has no genuine value and can instead cause serious issues. PUAs are designed to run intrusive advert campaigns, force-open unreliable/malicious sites, modify browsers and gather private data.

How did WebAdvancedSearch install on my computer?

PUAs are distributed through download/installation setups. 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, etc.) - increase the risk of unintentionally allowing bundled content into the system. Some PUAs have "official" download webpages. Intrusive advertisements proliferate these apps 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 strongly advised to research software before download/installation and/or purchase. Only official and verified download channels must be used. Unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders - commonly offer deceptive and/or bundled content, due to this - they are deemed to be untrustworthy. When downloading/installing, it is important to read terms, explore all possible options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, features, and so on. Intrusive ads appear legitimate and harmless, however they redirect to highly questionable sites (e.g. gambling, pornography, adult-dating, etc.). In case of encounters of such adverts/redirects, users must check the system and immediately remove all dubious applications and/or browser extensions/plug-ins from it. If your computer is already infected with WebAdvancedSearch, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
