Removal instructions for IndexerSource adware and the adverts it displays

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

What is IndexerSource?

IndexerSource is an application that our researchers discovered while inspecting new submissions to VirusTotal. After analyzing this piece of software, we learned that it operates as adware and is part of the AdLoad malware family.

IndexerSource adware

IndexerSource adware overview

Adware operates by enabling the placement of advertisements (e.g., pop-ups, banners, etc.) on visited websites and/or other interfaces. The adverts endorse various scams, untrustworthy/harmful webpages and software, and even malware. Additionally, some intrusive ads can execute scripts to download/install software stealthily.

Note that any genuine products encountered via these adverts are highly unlikely to be promoted by their developers. This endorsement is undertaken by scammers abusing the products' affiliate programs to obtain illegitimate commissions.

It is noteworthy that advertising-supported software might not display advertisements if the browser/system or user geolocation are incompatible, visits to specific sites are not made, or other conditions are not met. However, regardless of whether IndexerSource delivers ads - its presence endangers device/user safety.

Furthermore, this application may have browser hijacker qualities since they are common for AdLoad adware; however, we did not observe any during testing.

IndexerSource likely has data tracking abilities. Advertising-supported software typically gathers browsing-related information, personally identifiable details, usernames/passwords, credit card numbers, etc. The collected data can then be shared with and/or sold to third-parties (potentially, cyber criminals).

In summary, the presence of software like IndexerSource on devices can result in system infections, serious privacy issues, financial losses, and even identity theft.

Adware examples

We have analyzed thousands of apps within the adware classification; WheelInstant, AdvanceServices, and ExpressionCargo are just a couple of examples. This software usually appears legitimate and harmless. Users are lured into download/installation with promises of "handy" functionalities - however, they are rarely operational.

How did IndexerSource install on my computer?

Adware can be bundled with (packed alongside) regular programs. Download from dubious download channels (e.g., unofficial and freeware sites, P2P sharing networks, etc.) and rushed installations increase the risk of allowing bundled content into the system.

Intrusive adverts also spread advertising-supported software. Once clicked on, some of these ads can execute scripts to make downloads/installations without user permission. Fake Adobe Flash Player updaters/installers proliferate adware as well.

Additionally, dubious download pages and scam sites are used in distribution. Users typically enter these websites via redirects caused by pages using rogue advertising networks, mistyped URLs, spam browser notifications, intrusive advertisements, or installed adware (with browser force-opening capabilities).

How to avoid installation of adware?

We highly recommend researching software and downloading it from official/verified channels. When installing, it is crucial to read terms, explore possible options, use the "Custom" or "Advanced" settings, and opt-out of all additions.

We advise exercising caution when browsing since illegitimate and malicious content looks harmless. For example, intrusive ads appear ordinary yet redirect to unreliable/questionable websites (e.g., gambling, adult-dating, pornography, and so on).

If you experience such adverts/redirects, check the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with IndexerSource, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
