How to remove Docallisec adware from Mac?

What is Docallisec?

Docallisec is an adware-type application with browser hijacker traits. Following installation, it runs intrusive advertisement campaigns (i.e. delivers various ads), makes alterations to browser settings and promotes fake search engines. Most adware and browser hijackers have data tracking abilities and it is highly likely that Docallisec has such as well. Due to the dubious methods used to distribute this app, it is also deemed to be a PUA (Potentially Unwanted Application). One of the distribution techniques used for Docallisec is proliferation via fake Adobe Flash Player updates. Illegitimate software updaters/installers proliferate not just PUAs but trojans, ransomware and other malware.

Docallisec adware proliferated through fake Adobe Flash Player updater/installer

Adware enables the placement of pop-ups, surveys, banners and other intrusive advertisements - typically, on any visited website. These ads diminish the browsing experience, since they overlay page content and slow down the browsing speed. Additionally, once intrusive adverts are clicked on - they redirect to unreliable/malicious sites and some can even 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, every new browser tab/window opened and search query typed into the URL bar - redirect to the promoted address. Illegitimate search engines are seldom able to provide search results, so they redirect to Yahoo, Bing, Google and other genuine web-searching tools/services. Browser hijackers can also restrict/deny access to the browser's settings and/or reassign any permitted changes made. As mentioned in the introduction unwanted software commonly has data tracking abilities. It can monitor browsing activity (visited URLs, viewed pages, typed search queries, etc.) and gather personal information inferred from it (IP addresses, geolocations and other details). This sensitive data is often shared with and/or sold to third parties. Therefore, presence of PUAs on devices can result in system infections, financial losses, severe privacy issues and even identity theft. To protect device integrity and user safety - all suspicious applications and browser extensions/plug-ins must be eliminated without delay.

SectionBrowserSearchWebPortalExtendedToolSearchMainInfo - are some examples of other adware-type apps. They appear legitimate and useful. However, despite how good their advertised functionalities may sound - these features are usually nonoperational. This applies to practically all PUAs. Functionality, user convenience and safety are irrelevant, since the only purpose of unwanted software is to generate revenue for the developers. PUAs are designed to deliver intrusive ad campaigns, modify browsers, cause redirects and collect private information.

How did Docallisec install on my computer?

PUAs can be downloaded/installed together with other software. "Bundling" is the term used to define this deceptive marketing technique of pre-packing regular products with unwanted or malicious additions. By rushing through download/installation processes (e.g. by skipping steps and sections, etc.) - users risk unintentionally allowing bundled content into their devices. Select PUAs have "official" download webpages. Intrusive adverts proliferate these applications as well. Upon being clicked, they can execute scripts to stealthily download/install PUAs.

How to avoid installation of potentially unwanted applications?

It is strongly advised to research products prior to download/installation and/or purchase. Only official and verified download channels should be used. Untrustworthy sources, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - often offer dubious and/or bundled content. When downloading/installing, it is recommended to read terms, explore all possible options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, features, etc. Intrusive advertisements appear legitimate, however they redirect to various questionable pages (e.g. gambling, pornography, adult-dating, and so on). Should users encounter ads and/or redirects of this kind, they are to inspect their devices and immediately remove any suspect software found. If your computer is already infected with Docallisec, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
