What is Multi AdBlock?
Multi AdBlock is a browser extension endorsed as a tool capable of removing online advertisements. In fact, rather than eliminating ads, this fake adblocker delivers them. Due to this, it is categorized as adware.
Additionally, Multi AdBlock has data tracking capabilities, which are used to collect browsing-related information. Since most users download/install adware-type programs unintentionally, they are also classified as Potentially Unwanted Applications (PUAs).
Adware enables the placement of pop-ups, banners, surveys, coupons, and other intrusive advertisements on any visited website (or different interfaces). The delivered ads significantly diminish the browsing experience by overlaying page content and reducing browsing speed.
Furthermore, once clicked, intrusive ads can redirect to various misleading, deceptive/scam, and malicious websites. Some of these advertisements can even be triggered (when clicked) to execute scripts designed to download/install software (e.g., PUAs) without users' permission.
PUAs have varied dangerous functionality, and these functions can be in different combinations. For example, these apps can run intrusive advertisement campaigns and force-open dangerous websites.
Most PUAs (regardless of other capabilities) 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, the presence of unwanted software on devices can result in system infections, serious privacy issues, financial loss, and identity theft. To protect device and user safety, all dubious applications and browser extensions/plug-ins must be removed immediately upon detection.

SketchBall, Clear History, Chrome 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 most PUAs.
The sole purpose of these unwanted apps is to generate revenue for the developers. Rather than delivering any real value, PUAs run intrusive advertisement campaigns, cause redirects, modify browsers (browser hijackers), and collect private data.
How did Multi AdBlock install on my computer?
PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".
By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well. When clicked, the ads can execute scripts to download/install these applications without users' permission.
Some PUAs (including Multi AdBlock) have "official" download web pages from which they can be downloaded.
How to avoid installation of potentially unwanted applications
You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.
When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on.
Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others). If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately.
Installed programs must be activated and updated with tools or implemented functions that are provided by the official developers. No other third party, unofficial tools should be used.
Note that it is illegal to activate licensed software with ‘cracking’ tools. Files and programs should be downloaded from official websites and via direct download links. Avoid third party installers and the tools/sources mentioned above.
Do not open website links or files in irrelevant emails that are received from unknown, suspicious addresses. These bogus emails are often disguised as official and important. Regularly, scan your computer with reputable, up-to-date antivirus or anti-spyware software.
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.
