How to remove Multi AdBlock adware and the advertisements it delivers?

Also Known As: Ads by Multi AdBlock
Type: Adware
Damage level: Medium

What is Multi AdBlock?

Multi AdBlock is a browser extension endorsed as a tool capable of removing online advertisements. Instead of eliminating ads, this fake adblocker delivers them. Due to this, it is categorized as adware. Additionally, Multi AdBlock has data tracking abilities that are used to collect browsing-related information.

Since most users download/install adware-types unintentionally, they are also deemed to be PUAs (Potentially Unwanted Applications).

Multi AdBlock adware asking to be permitted to track data

Adware enables the placement of pop-ups, banners, surveys, coupons, and other intrusive advertisements - on any visited website (or different interfaces). The delivered adverts seriously diminish the browsing experience by overlaying page content and slowing down the browsing speed.

Furthermore, once clicked on, intrusive ads redirect to various misleading, deceptive/scam, and malicious websites. Some of these advertisements can even be triggered (by being clicked on) to execute scripts designed to download/install software (e.g., PUAs) without user permission.

PUAs can have varied heinous functionalities, and these functions can be in different combinations. For example, these apps can run intrusive advertisement campaigns and/or force-open dangerous websites. Most PUAs (regardless of other abilities) can track data, and this applies to Multi AdBlock.

Information of interest includes: browsing and search engine histories, IP addresses, geolocations, and even personally identifiable details. PUA developers monetize the gathered data by sharing it with and/or selling it to third-parties (potentially, cyber criminals).

In summary, presence of unwanted software on devices can result in system infections, severe privacy issues, financial losses, and identity theft. To protect device and user safety, all dubious applications and browser extensions/plug-ins must be removed immediately upon detection.

SketchBallClear HistoryChrome Tools, and Go Easy Directions Promos are some examples of software within the adware classification. It usually appears legitimate and offers a wide variety of "useful" functionalities. However, the promised functions are seldom operational. In fact, this is true of nearly all PUAs.

The sole purpose of unwanted apps is to generate revenue for the developers. Therefore, instead of delivering on any promises, PUAs can run intrusive advertisement campaigns, cause redirects, modify browsers (browser hijackers), and collect private data.

How did Multi AdBlock install on my computer?

Select PUAs (e.g., Multi AdBlock) have "official" promotional/download webpages. These applications can also be downloaded/installed together with other programs. This false marketing tactic of packing regular software with unwanted or malicious additions - is called "bundling".

Rushed download/installation processes (e.g., ignored terms, skipped steps and sections, etc.) increase the risk of inadvertently allowing bundled content into the system. When clicked on, intrusive ads can execute scripts to stealthily download/install PUAs.

How to avoid installation of potentially unwanted applications?

It is recommended to research software before download/installation and/or purchase. Only official and verified download channels should be used.

Untrustworthy sources, e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks (Torrent clients, eMule, Gnutella, etc.), and other third-party downloaders - commonly offer harmful and/or bundled content. Download and installation processes must be treated with care.

Therefore, it is important to read terms, explore all possible options, use the "Custom/Advanced" settings and opt-out from supplementary apps, tools, functions, and other additions.

Intrusive advertisements appear ordinary and innocuous; however, they redirect to various questionable and unreliable websites (e.g., adult-dating, pornography, gambling, and so on).

In case of encounters with such adverts and/or redirects, 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 Multi AdBlock, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
