How to remove ActionHow adware

Also Known As: Ads by ActionHow
Type: Mac Virus
Damage level: Medium

What is ActionHow?

ActionHow software is promoted as improving the browsing experience. It is supposedly capable of providing fast searches, accurate results, and so on. In fact, this adware diminishes the browsing experience by running intrusive advertisement campaigns (i.e., delivering unwanted and even harmful ads).

Most adware-type apps also have data tracking capabilities. Due to its dubious proliferation methods, ActionHow is also categorized as a Potentially Unwanted Application (PUA).

ActionHow adware

Adware-type apps deliver a wide variety of advertisements. For example, pop-ups, banners, surveys, coupons, etc. They affect browsing by slowing browsing speed and limiting website visibility (by overlaying page content). Furthermore, when clicked, these ads redirect to various sale-oriented, untrustworthy/rogue, compromised, deceptive/scam and even malicious web pages.

Clicking can even trigger them to download/install software without users' permission. An example of content infiltrated into devices in this fashion are PUAs. Note that adware is commonly capable of monitoring users' browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collecting personal information (IP addresses, geolocations and other details).

This sensitive data can then be shared with third parties (potentially, cyber criminals) seeking to misuse it for financial gain. Therefore, adware can cause browser and system infiltration/infections and also lead to serious privacy issues, financial loss or even identity theft.

To protect device integrity and ensure user safety, you are strongly advised to remove all suspicious applications and/or browser extensions/plug-ins immediately upon detection.

Adware is a common form of PUA. Other examples include ExploreSearchResultsGlobalAdviseSearch and EngineFiles. They may seem legitimate and often tempt users into downloading/installing them with offers of "useful" and "beneficial" functions. In fact, these features rarely work as promised and, in most cases, are nonoperational.

In fact, this applies to all PUAs. At first glance, they may seem no different from normal software. Following installation, however, it is clear that they are nonfunctional and useless. The only purpose of PUAs is to generate profit for the developers at the expense of users.

They run intrusive advertisement campaigns, force-open untrustworthy and malicious sites, hijack browsers and promote fake search engines, and gather private data.

How did ActionHow install on my computer?

PUAs can be downloaded/installed together with other software. This deceptive marketing technique of pre-packing regular products with unwanted or malicious content is called "bundling".

By rushing through download and installation processes (e.g. ignoring terms, using pre-set options, skipping steps and sections, etc.), users endanger their devices with potential infiltration and infections via bundled applications. Some PUAs also have "official" download pages. Once clicked, intrusive ads can execute scripts to stealthily download/install PUAs.

How to avoid installation of potentially unwanted applications

All content should be researched to verify its legitimacy, prior to download/installation. Use only official and verified download channels. Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule, etc.), unofficial and free file-hosting websites, third party downloaders and similar are untrusted sources and should be avoided.

Treat download and installation processes with caution. When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features and so on.

Intrusive advertisements may seem legitimate and harmless, however, they can redirect to dubious web pages (e.g. pornography, adult-dating, gambling and many others). If you encounter ads/redirects of this kind, inspect the system and remove all suspect applications and/or browser extensions/plug-ins immediately.

If your computer is already infected with ActionHow, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
