Adrozek adware removal instructions
What is Adrozek?
Adrozek is a malicious browser modifier, classified as adware. It operates by infiltrating browsers and injecting untrustworthy and malicious ads into them. However, Adrozek can do more than just run intrusive advertisement campaigns. This software is designed to collect information extracted from browsers and attempts to gain a better foothold on the device through manipulation of browser settings and extensions, as well as installation of additional ones. While during research, Adrozek did not always successfully carry out its intended purposes, it nonetheless posses a significant threat to device/user safety. Due to the dubious methods used to proliferate adware, such apps are also considered to be PUAs (Potentially Unwanted Applications).
Adrozek targets Google Chrome, Mozilla Firefox, Microsoft Edge and Yandex browsers. How it affects the browsers differs, however in general terms - it modifies browser settings and delivers deceptive, potentially virulent adverts. The modifications can include: circumventing or disabling security defenses, disguising as legitimate extensions, invisibility on the task bar, running in incognito/private mode, disabling updates, executing scripts on visited websites without user permission, disabling safe mode, etc. The primary purpose of Adrozek is to run advertisement campaigns. It does so by injecting the ads into search results and in some cases - it may even overlay genuine advertisements with its own on visited sites. Once the injected false search results and/or delivered adverts are clicked on - they redirect to various unreliable and possibly malicious websites. Furthermore, the advertisements and promoted webpages may be able to infiltrate unwanted or even malicious software into browsers/systems.
While Adrozek has been observed promoting relatively innocuous sites, it has likewise been noted to download/install additional content. What is more, Adrozek attempts to extract and exfiltrate data from compromised browsers. Typically, software of this type targets the following information: browsing and search engine histories, IP (Internet Protocol) addresses, geolocations, personally identifiable details, credit card numbers, account log-in credentials (i.e. IDs, usernames, passwords), and so forth. To summarize, presence of Adrozek on devices can result in browser/system infections, severe privacy issues, financial losses and even identity theft. Therefore, it is strongly recommended to remove all suspicious applications and browser extensions/plug-ins immediately upon detection.

AdBlock Stream, Movie Finder, Media Convert Pro Promos and OneUpdater are some examples of other adware-type applications. They appear legitimate and harmless. Users are often enticed into download/installation with offers of various "useful" features. However, the promised functionalities are rarely operational. In fact, this applies to nearly all PUAs. The sole purpose of unwanted apps is to generate profit for the developers; to users - they have no real value and may cause serious problems. PUAs are designed to run intrusive ad campaigns, force-open untrustworthy and dangerous webpages, hijack browsers, and collect sensitive/private data.
How did Adrozek install on my computer?
PUAs can be downloaded/installed together with other programs. This deceptive marketing technique of packing regular software with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g. skipped steps and sections, etc.) increase the risk of inadvertently allowing bundled content into the system. Select PUAs have "official" promotional pages, from which they can be downloaded. Intrusive advertisements infiltrate these apps into systems by executing scripts to stealthily download/install them. The ads are triggered to initiate PUA download/installation - when they are clicked on.
How to avoid installation of potentially unwanted applications?
It is highly recommended to research software products before download/installation and/or purchase. All downloads should be done only from official and verified sources. Since dubious channels, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer harmful and/or bundled content. When downloading/installing, it is important to read terms, study all available options, use the "Custom" or "Advanced" settings and opt-out from additional apps, tools, functions, etc. Intrusive adverts appear ordinary, however they redirect to unreliable and questionable sites (e.g. adult-dating, gambling, pornography, and so on). In case of encounters with ads and/or redirects of this kind, the system must be inspected and all suspect applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with Adrozek, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
