How to uninstall the TopProcesser adware from your operating system?
Written by Tomas Meskauskas on (updated)
What is TopProcesser?
TopProcesser is an adware-type application with browser hijacker qualities. It operates by delivering intrusive advert campaigns and promoting fake search engines through modifications to browser settings. Additionally, software of this type typically has data tracking abilities.
Due to the dubious methods used to distribute adware and browser hijackers, they are also categorized as PUAs (Potentially Unwanted Applications). TopProcesser has been observed being proliferated via fake Adobe Flash Player updates, which are known to spread PUAs and malware (e.g., trojans, ransomware, cryptominers, etc.)
TopProcesser adware in detail
Adware delivers pop-ups, banners, coupons, surveys, and other intrusive ads. This graphical content can be displayed on any visited website and/or different interfaces. These advertisements diminish the browsing experience by overlying webpage content and slowing down the browsing speed.
Furthermore, intrusive adverts endanger device and user safety. They promote various sale-based, untrustworthy, deceptive/scam, compromised, and malicious sites. Some intrusive ads can be triggered (by being clicked) to stealthily download/install software (e.g., PUAs).
Browser hijackers reassign browsers' homepage, default search engine, and new tab/window URLs - to fake web searcher addresses. Hence, with such a piece of software installed: every new browser tab/window opened and search query typed into the URL bar - redirect to TopProcesser.
Fraudulent search engines usually cannot provide search results, so they redirect to (or cause redirection chains ending with) Google, Yahoo, Bing, and other genuine ones. It is impossible to recover a browser without removing the browser hijacker because they can restrict/deny access to the browser settings and/or undo user-made changes.
What is more, most PUAs (adware and browser hijacker included) can track data. Targeted information includes (but is not limited to): URLs visited, webpages viewed, search queries typed, IP addresses/ geolocations, and personally identifiable details.
The gathered data is then monetized by being shared with and/or sold to third-parties. In summary, the presence of unwanted apps on devices can lead to system infections, severe privacy issues, financial losses, and identity theft. Therefore, it is crucial to remove all suspicious applications and browser extensions/plug-ins without delay.

Adware in general
DesktopInput, OriginalSearchTech, DefaultUpgrade, ConfigAccess, and IndexerProject are some examples of apps within the adware category. They appear legitimate and offer "handy" features. However, the promised functions are seldom operational.
Nearly all PUAs entice users into download/installation with promises of fake functionalities. The only aim of unwanted software is to generate profit for the developers; they have no real value to users. PUAs are designed to run intrusive advertisement campaigns, cause redirects, hijack browsers, and collect private data.
How did TopProcesser install on my computer?
PUAs are distributed through download/installation setups of other products. This false marketing tactic of packing regular programs with unwanted/malicious additions - is called "bundling". Rushed download/installations processes (e.g., skipped steps and sections, etc.) increase the risk of allowing bundled content into the device.
Intrusive advertisements are used to proliferate PUAs as well. Once clicked on, the adverts can execute scripts to download/install these applications without user permission. PUAs may also have "official" promotional pages from which they can be downloaded and/or purchased.
How to avoid installation of potentially unwanted applications?
It is recommended to research products prior to download/installation and/or purchase. Additionally, only official and trustworthy download channels must be used. Dubious sources, e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled and harmful content.
When downloading/installing, it is advised to read terms, study all possible options, use the "Custom/Advanced" settings to opt-out from additional apps, tools, features, etc. Intrusive advertisements appear legitimate; however, they redirect to various unreliable sites (e.g., gambling, pornography, adult-dating, and so on).
In case of encounters with ads and/or redirects of this kind, the system must be checked and all suspect applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with TopProcesser, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
