BrowserState adware in detail

BrowserState generates revenue for its developer by displaying banners, pop-ups, surveys, coupons, or other advertisements. Ads displayed by BrowserState are likely to be designed to open shady websites. Also, those ads may be designed to run certain scripts and then download or even install unwanted software.

It is common for apps like BrowserState to be designed to show ads used to promote websites similar to "Error Code: #2c522hq8wwj791", "Receive iPhone 12", "Apple Platform Security", and other sites created with the purpose to trick visitors into providing credit card details or other personal information, or into installing PUAs.

Also, this application functions as a browser hijacker. Browser hijackers change the settings of a hijacked browser to promote a fake search engine (its address). In most cases, apps of his type change the address of a default search engine, homepage, and new tab and do not allow users to undo these changes until they are uninstalled.

Another reason not to have BrowserState installed/to remove this app as soon as possible is that it may be designed to collect information related to browsing habits and (or) sensitive information. It might be designed to collect IP addresses, entered search queries, geolocations, and other data.

Also, BrowserState could be designed to collect data that its developers could misuse for marketing purposes, sell it to third parties, steal identities, hijack online accounts, make fraudulent purchases, transactions, or other malicious purposes. In one way or another, this should never be installed.

Adware in general

Adware is a type of software designed to display unwanted advertisements. Quite often, it can collect various information and (or) change browser's settings as well. It is strongly recommended not to install software of this type even if it is advertised as legitimate, useful software. More adware examples are ExpandedValue, AlgorithmInput, and SmartTechLookup.

How did BrowserState install on my computer?

In most cases, people download and install potentially unwanted applications when these apps are distributed by bundling them with other programs. In other words, when PUAs are included in downloaders, installers as optional offers. Offers to download or install bundled applications can be declined before finishing downloads or installations.

Downloaders and installers used to distribute PUAs have "Custom", "Advanced" and other similar settings (or ticked checkboxes). Users can use those settings to deselect unwanted apps. Sometimes, users download, installs PUAs by clicking on deceptive ads designed to run certain scripts. Typically, those ads appear on dubious, untrustworthy pages.

How to avoid installation of potentially unwanted applications?

Downloaders and installers with settings like "Advanced" "Custom", "Manual", etc., or ticked checkboxes should be examined. It is common for the aforementioned downloaders, installers to be used to distribute potentially unwanted applications.

Files and applications should be downloaded from official web pages and via direct links. It is not recommended to use unofficial websites, third-party downloaders, Peer-to-Peer networks like torrent clients, eMule, or other sources, channels of this kind. Third-party installers should not be used as well.

Advertisements on questionable pages should not be clicked. Pretty often, those advertisements are designed to open other sites of this kind or execute scripts to download or install potentially malicious software. Unwanted, unknown, or suspicious apps (extensions, plug-ins, add-ons) installed on a browser should be removed.

Any software of this kind that is installed on the operating system should be uninstalled too. If your computer is already infected with BrowserState, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
