What is Quantum Ad Blocker?
Quantum Ad Blocker is a rogue browser extension, which is endorsed as an adblocker - a tool that blocks ads on visited websites. However, this piece of software operates by delivering intrusive advertisements instead. Due to this, Quantum Ad Blocker is classified as adware and a PUA (Potentially Unwanted Application).
Quantum Ad Blocker adware in detail
Adware enables the placement of third-party graphical content (e.g., pop-ups, banners, coupons, etc.) on any visited website and/or different interfaces. The delivered adverts severely diminish the browsing experience and endanger device/user safety.
Intrusive advertisements promote various sale-oriented, rogue, deceptive/scam, and malicious sites. Furthermore, once clicked on, the ads can download/install software (e.g., PUAs) without user permission.
Adware typically has data tracking abilities, and Quantum Ad Blocker is not an exception to this. Targeted information includes (but is not limited to) browsing and search engine histories, IP addresses, and personally identifiable details. The gathered data is then shared with and/or sold to third-parties (potentially, cyber criminals).
In summary, the presence of unwanted software on devices can result in system infections, serious privacy issues, financial losses, and even identity theft.

Adware in general
Reputation Lookup, Movie Finder, Simply Convert Files, and AdBlock 360 are some examples of adware. It appears harmless and offers "handy" features, which are usually nonoperational. This applies to practically all PUAs. Instead of delivering on any promises, unwanted apps can run intrusive advertisement campaigns, cause redirects, hijack browsers, and collect private information.
How did Quantum Ad Blocker install on my computer?
PUAs are spread using the "bundling" marketing technique - packing ordinary programs with unwanted/malicious additions. Rushed download/installation processes increase the risk of unintentionally allowing bundled content into the system.
Intrusive adverts are used to proliferate PUAs as well. Upon being clicked, the ads can execute scripts to make stealthy downloads/installations. Some PUAs (e.g., Quantum Ad Blocker) also have "official" promotional/download webpages.
How to avoid installation of potentially unwanted applications?
It is advised to research software and download from official/verified sources. Untrustworthy download channels, e.g., Peer-to-Peer sharing networks, unofficial and free file-hosting sites, etc. - often offer bundled and hazardous content.
When downloading/installing, it is recommended to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out from all additions. Intrusive advertisements appear legitimate; however, they redirect to highly questionable websites (e.g., pornography, adult-dating, gambling, etc.).
In case of encounters with ads and/or redirects of this kind, the system must be inspected and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with Quantum Ad Blocker, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
