How to remove ActivityInput from Mac?

What is ActivityInput?

In most cases users download and install apps like ActivityInput unknowingly, therefore, they are called potentially unwanted applications (PUAs). Typically, they are distributed by using deceptive methods. This particular app is distributed via deceptive installer that is designed to look like the installer for Adobe Flash Player. ActivityInput is designed to serve advertisements and promote a fake search engine (its address) by modifying browser's settings. It functions as adware and a browser hijacker. It is likely that this app is designed to collect browsing data and/or other details.

ActivityInput adware

Some examples of ads that apps like ActivityInput serve are banners, surveys, pop-up ads, coupons. It is common that those ads are designed to promote (open) shady pages. Although, in some cases they can be designed to download and/or install unwanted software by executing certain scripts. Also, ActivityInput modifies browser's settings such as the address of a default search engine, homepage and new tab. Like most browser hijackers, it changes those addresses to an address of some fake search engine. Therefore, users who have apps like ActivityInput cannot avoid having to visit a certain address when they open a browser, new tab and enter search queries into URL bar. Additionally, it is likely that ActivityInput collects data like IP addresses, entered search queries, addresses of visited websites, geolocations, and/or other browsing-related information. It is possible that it gathers sensitive information as well. In such case collected data could be misused to generate revenue by selling it to third parties (potentially cyber criminals) or in other ways, which could cause users problems related to browsing safety, online privacy, they may even become victims of identity theft.

ActivityInput is virtually identical to StandardBoost, SkilledObject and GuideRecord. What most of them have in common is that they serve ads and modify browser's settings. It is worthwhile to mention that such apps do not include any features or are useful to their users in any way. Their main purpose is to generate revenue for their developers.

How did ActivityInput install on my computer?

ActivityInput is distributed via deceptive installer that is disguised as the installer for Adobe Flash Player. It is common that fake, unofficial installers are used to distribute malware as well, for example, ransomware, Trojan-type malware. Also, PUAs often are distributed by including them in download and/or installation setups of other programs as additional offers. This distribution/promotion method is known as "bundling". Typically, offers to download and/or install PUAs can be declined via "Custom", "Advanced" and other similar settings, or by unticking certain checkboxes that certain download and/or installation setups have. When users do not do that, they agree with offers to download and/or install unwanted apps. Another way to unintentionally download and/or install various PUAs is by clicking deceptive ads that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

It is recommended to always check what are "Custom", "Advanced", "Manual" and other settings of download and/or installation setup and see if they can be used to decline offers to download and/or install unwanted software. Also, it is advised not to download (and/or install) software through untrustworthy, unofficial websites, torrent clients, eMule (and other Peer-to-Peer networks), third party downloaders, installers etc. The safest way to download files and programs is by using official websites and direct download links. Advertisements that are shown on questionable pages should not be clicked as well. The problem with those ads is that they could be designed to open potentially malicious pages or cause unwanted downloads, or even installations. Any unwanted, suspicious extension, plug-in or add-on that is already installed on a browser should be removed. The same should be done with software of this kind that is installed on the operating system. If your computer is already infected with ActivityInput, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
