What Is ExplorerIndex?
ExplorerIndex is categorized as adware and potentially unwanted program which belongs to the AdLoad adware family, also known as Trojan.AdLoad. It is noteworthy that the trojan component makes it more threatening than most adware. It means that the program can open a backdoor on the system to drop additional suspicious software, and collect personal, browser and/or system information.
What happens when ExplorerIndex sneaks into your Mac?
First, you could be exposed to aggressive advertising campaigns, as a result of which numerous ads will be shown to you. These ads could further activate intrusive redirects to phishing pages. Another consequence of having ExplorerIndex run on your Mac is unsolicited data collection that could happen either via the adware or the trojan component of AdLoad. The threat could also install a keylogging component.
Because of these risks, it is recommended to remove ExplorerIndex and all its files.

ExplorerIndex – Overview of Capabilities
Adware programs, such as ExplorerIndex, typically display ads and coupons for websites related to online shopping. The ads may seem convincing, offering you various discounts and deals on items you want to purchase. However, don’t be fooled – such programs can be quite intrusive and persistent.
Once this piece of adware is installed and started on your Mac, it is highly likely to initiate a series of modifications, including browser settings that will enable the generation of said advertisements. Furthermore, the program may also be able to affect the settings of popular browsers such as Mozilla Firefox, Google Chrome, Internet Explorer, and Safari.
Having adware installed and running on your Mac is also associated with further risks. First, adware such as ExplorerIndex could make your your browser sluggish, which in turn could diminish significantly your browsing experience. And second, some of the ads may redirect you to poorly secured web pages compromised by hackers.
ExplorerIndex – Distribution
Several techniques are usually deployed for the distribution of this adware. A widely spread distribution technique is software bundling. Bundling revolves around programs that pretend to be useful and legit but come bundled with ad-supported apps.
The purpose of bundling is quick monetization. Commonly used software may deliver unwanted apps such as ExplorerIndex. This includes media players, file converters, weather toolbars, online streaming apps, etc.
The installers of these programs often present optional offers or free extras. At the same time, they are not designed to appropriately disclose information about added apps. That’s how users fail to notice their presence during the installation of whatever software they wanted to download.
Other possible reasons for having the adware dropped on your system include interacting with suspicious pages (torrenting and online streaming websites, adult pages, free online games, etc.). On these pages, you may have clicked on suspicious links, banners, and offers. The result is an unnoticed download and installation of a potentially unwanted program, such as ExplorerIndex.
A very wide-spread propagation technique that AdLoad variants utilize is using a fake Flash Player update. Your browser may generate a fake error message, claiming that “Adobe Flash Player Is Out of Date”. Interacting with the message, like clicking on the download button it provides, will surely install an adware on your Mac.
N.B. Once started on your Mac, such a program could access all installed browsers’ settings to apply significant changes. One of these changes often affects the default search engine in your preferred web browser. If your default search engine is altered without your consent, then don’t waste time but go check your macOS security. This problem is a definite sign that a suspicious piece of software has sneaked into your system.
Furthermore, as long as files associated with the adware are running on your Mac, you may be a victim of unsolicited data collection.
By activating different tracking technologies like cookies, web beacons, javascript, or even Trojans, the ad-supported application may become able to obtain a long list of sensitive details, including:
- Visited URLs and websites
- Browser’s home page
- Search queries
- Search queries on the visited web pages
- Type of used browser
- Operating system type
- Internet protocol (IP) address
- Geographic location
- The domain name of the current Internet service provider (ISP)
- Banking credentials
- Entered keystrokes
Shady adware developers may use your data records in targeted advertising campaigns. Once the data is available on their servers, it can be used for the identification of your online interests. Ads delivered by unwanted programs may target your interests. At worst, data records will be released on dark web markets for additional revenue.
How Does ExplorerIndex Achieve Persistence on macOS?
AdLoad variants have the capability to install a persistence agent in the Library LaunchAgents folder. This way the adware becomes persistence on the machine, and requires specific technical approach to remove completely.
Is ExplorerIndex a Virus?
By definition, ExplorerIndex does not fit to the technical description of computer viruses. A computer virus is the type of program that replicates itself upon execution and modifies other programs by inserting its own code. Once the replication happens, the affected areas are “infected” with the computer virus. This adware does not have these capabilities.
However, the app’s behavior fits the description of adware and potentially unwanted programs. AdLoad variants are also known for their backdoor capabilities. In other words, despite not being a real computer virus, ExplorerIndex is threatening to your online security and should be removed from your Mac.

The guide below will reveal all needed removal steps, including manual and automatic actions. Due to the adware’s persistence, we recommend using both approaches.
