How to remove OperativeMachine adware

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

What is OperativeMachine?

OperativeMachine is classified as adware because it generates advertisements. Note that it also functions as a browser hijacker, modifying browser settings to promote a fake search engine.

Typically, users do not download or install apps such as OperativeMachine intentionally and, for this reason, they are classified as potentially unwanted applications (PUAs). This particular app is distributed via a fake installer for Adobe Flash Player.

OperativeMachine adware

OperativeMachine adware overview

Some examples of ads generated by OperativeMachine and similar apps include coupons, banners, surveys, and pop-ups. These can open other bogus web pages or download/install unwanted apps by running certain scripts.

Furthermore, OperativeMachine promotes a fake search engine by changing browser settings. Typically, apps of this type change the default search engine, homepage, and new tab. Users cannot remove the address of the fake search engine from browser settings unless they first uninstall the browser hijacker that promotes it.

OperativeMachine might also gather browsing data (IP addresses, geolocations, entered search queries, addresses of visited pages) and even private, sensitive information. The data could be monetized by selling it to third parties (potentially, cyber criminals) or in other ways. Therefore, users might become victims of identity theft, encounter problems relating to browsing safety and online privacy, and experience other issues.

Adware examples

ActivityInput, StandardBoost and SkilledObject are other adware examples. Most apps of this type generate ads. They are useless to regular users, even if they are advertised as legitimate, useful apps.

If PUAs are already installed on the browser and/or computer, remove them immediately.

How did OperativeMachine install on my computer?

OperativeMachine is distributed via a fake Adobe Flash Player installer. Note that these installers can be used to distribute ransomwareTrojan-type malware, and other rogue software of this kind.

PUAs are also distributed via download/installation set-ups of other products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling".

Rushing download/installation processes (e.g. ignoring terms, skipping steps and settings, etc.) increases the risk of inadvertently allowing bundled content into the system.

Some PUAs have "official" download sites. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications?

Download software and files from official websites and via direct links. It is not safe to use torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, unofficial websites or other sources of this kind.

Avoid third party installers. Check "Advanced", "Custom" and other settings, and decline offers to download or install unwanted software. Do not click ads that are displayed on dubious websites, since they can open other untrusted websites or even cause unwanted downloads and installations.

Remove any unwanted, suspicious applications (extensions, add-ons, and plug-ins) that are installed on the browser. The same should be applied to programs of this kind that are installed on the operating system.

Regularly scan your computer with reputable antivirus or anti-spyware software and keep this software up to date.

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

Frequently Asked Questions (FAQ)

What harm can adware cause?

Adware-delivered ads promote content that may cause severe issues (e.g., system infections, financial losses, etc.). The software can also decrease browsing quality and system performance. Advertising-supported software usually has data-tacking functionalities – hence, it is classed as a privacy threat.

What does adware do?

Adware is designed to run intrusive ad campaigns. The software's primary functions can include displaying ads on visited sites or other interfaces, generating redirects, and collecting sensitive information.

How do adware developers generate revenue?

Adware developers profit primarily through affiliate programs by promoting content (e.g., websites, software, products, services, etc.).

Will Combo Cleaner remove OperativeMachine adware?

Yes, Combo Cleaner can scan devices and eliminate detected adware-type apps. It must be mentioned that manual removal (unaided by security programs) might be ineffective. In some instances, file leftovers stay hidden within the system – after the advertising-supported software has been manually removed. What is more, the remnants can continue to run and cause problems. Therefore, it is essential to eliminate adware and other undesirable software thoroughly.
