OBERONBOOSTER removal instructions

What is OBERONBOOSTER?

The OBERONBOOSTER program is advertised as an operating system optimization tool, however, it is distributed through various download/installation set-ups. Many people unintentionally download and install programs that are included in the set-ups of other programs. Therefore, OBERONBOOSTER is classified as a potentially unwanted application (PUA).

OBERONBOOSTER unwanted application

OBERONBOOSTER supposedly optimizes system startup, defragments disks, optimizes various services, cleans hard drives and the registry, and improves computer performance in other ways. It allows users to scan the operating system for unnecessary files, errors and other items that might be slowing down the operating system. Users can optimize systems with OBERONBOOSTER free of charge for one month, after which they must pay for activation. As mentioned, OBERONBOOSTER is categorized as PUA. Therefore, you are advised against paying for software of this type. In some cases, PUAs that supposedly optimize systems, fix errors, remove viruses, etc., actually generate fake scan results - they do not fix any problems and are designed only to trick users into paying for the rogue software. It is unknown whether OBERONBOOSTER provides fake scan results, however, this is a strong possibility. Note that developers often use download/installation set-ups to distribute multiple PUAs at once. Therefore, users who have OBERONBOOSTER installed on their computers might also have installed other PUAs such as browser hijackers and adware. Browser hijacking apps promote fake search engines by changing certain browser settings and collecting browsing-related data. In some cases, these apps record personal, sensitive information as well. The developers generate revenue by selling the information to third parties (potentially, cyber criminals) who misuse it in other ways. Adware-type applications can also track information. They also feed users with intrusive advertisements that open dubious web pages or download/install unwanted apps. These PUAs can cause a number of problems. For example, users might become victims of identity theft, experience problems relating to browsing safety, privacy, and other issues. Therefore, never trust OBERONBOOSTER or other PUAs and do not download or install them.

More examples of PUAs that share similarities with OBERONBOOSTER include Max Utilities, Max Uninstaller and DiskFixer. Most are distributed through the download or installation set-ups of other software, and supposedly provide various features. In fact, they are useless and designed only to extort money from unsuspecting users.

How did potentially unwanted applications install on my computer?

OBERONBOOSTER if often included in the setup of an unofficial Microsoft Office activation ('cracking') tool, which supposedly bypasses activation free of charge. Note that it is illegal to use such tools. PUAs are commonly included into the download or installation set-ups. This distribution method is called "bundling" - developers use it to trick people into downloading and installing PAUs together with other software that people wish to acquire intentionally. In most cases, offers to download/install additionally-included programs can be found in settings such as "Advanced", "Custom", and other similar parts. Many people fail to check or change these settings, thereby inadvertently agreeing with offers to download or install rogue software.

How to avoid installation of potentially unwanted applications

It is not safe to download or install software/files via dubious websites, using third party downloaders, installers, Peer-to-Peer networks (i.e., torrent clients, eMule), or other channels/tools of this kind. We advise you to download all software from official websites and using direct download links. Additionally, check "Advanced", "Custom", "Manual" and other similar options of the software set-ups, especially it the software is free. Dismiss any offers to download or install unwanted apps. Avoid clicking intrusive advertisements, especially those displayed on dubious web pages, since they can cause redirects to untrusted, potentially malicious websites. In some cases, they cause unwanted downloads and installations. If unwanted redirects happen or intrusive ads appear regularly, check your browser for unwanted extensions, add-ons and plug-ins, and uninstall them. Also remove programs of this type that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
