Is OberonBooster a real security program?

From our report of Mar 2020 · not reviewed since

OBERONBOOSTER is the program that supposedly is designed to optimize and speed up the computer but is considered to be not safe

OberonBooster is a rogue system tool that offers the free version for thirty days, so you can try all those alleged features before you purchase the useless full version of this tool. The tool should clean the disk and registry from unnecessary entries and files, optimize the performance, and affect the speed of the device, improve the time online.

However, this is an undesired program that shows predetermined issues and solutions for false errors, so you can fall for the scam and believe that all the problems are related to your device and pay for the full license of this "assistant". But the payment for 30 days of all functions costs you at least $70 or can go up to $210 for a 120-day subscription.

Nevertheless, there is no need to install the free version of this program or pay for the licensed version, because all the functionalities are false and not that valuable, int he first place.

OBERONBOOSTER virus is considered to be a potentially unwanted program for the questionable distribution method, in the first place. Additionally, this application is, in rare cases, installed by users themselves. More often, the promotional content of this tool triggers the download of the setup file and the PUP installation.

OBERONBOOSTER is the supposed system optimizer that should be a useful software component, so people can fix various system problems and improve the performance or even the speed of their machines. It is promoted as a valuable software online, on the official and other deceptive sites, but in most cases, PUA gets spread using software bundles - a technique that developers use by compiling various installers into one pack.

Even though it gets distributed around the web OberonBooster gets installed by the users themselves when they fall for the tricks used on the official site creators of this PUP have launched. These pages trigger direct downloads, and the software bundling method distributes installers packed with free software or cracked programs in file sharing sites and similar services.

OBERONBOOSTER.com can be one of many deceptive sites where such programs get distributed because criminals and scammers, in general, make fake websites where threats get promoted and include various additional programs or even malware applications more severe than the PUP itself.

You may need to remove OberonBooster and other intruders at the same time when the potentially unwanted program gets more time on your machine because these programs can easily infiltrate the system silently and add other programs without noticing you or asking for the permission. However, the more time infection has the more system changes it can make.

OberonBooster is capable of altering settings and preferences of your computer to affect the persistence of the application and manage needed functions that can affect the removal or detection processes and the main technique - showing false scan results.

Also, probably the only function that PUP actually can have is registry cleaning. Unfortunately, it is not the best feature that software could have because modifications made in such part of the machine may cause issues, corruption of certain programs, and performance.

OberonBooster removal should include and repair procedures needed for the system issues that can be caused by the unwanted program. You can try to uninstall this application manually, then run a proper anti-malware tool that can get rid of the traces of shady PUP.

You may not recognize issues caused by the application, but proper programs can find those affected registry entries and corrupted system files.

OberonBooster is a registry cleaner supposedly, but there are many issues regarding the activities and functions that such rogue tools have, so dealing with alleged problems can help neither with issues listed after the false scan or real problem- PUP infection. PUPs can alter other parts of the system and trigger security issues without showing any adware-type symptoms that could indicate a browser-based intruder or undesired program.

OBERONBOOSTER is marked as untrustworthy by anti-malware scanners and tools. It is also categorized as a potentially unwanted program, so even when you installed the application yourself, make sure to delete the shady optimizer completely. There is no need to keep it running on the device when it is not reporting real problems or fixing them properly.

How OberonBooster got on your PC

From our report of Mar 2020 · not reviewed since

You may download and install the program yourself by falling for the promotional material online or encountering the official site designed to spread the PUP.

More frequently, the application is spread by the potentially unwanted programs or with the help of bundling techniques that allow pre-packing freeware with these undesired applications.

Intrusive advertisements, pop-ups, or banners show various misleading information and triggers direct downloads of unwanted applications or hides the extra software included in the installation setups. You need to go through EULA and Privacy Policy sections to make sure that the source, the website that you selected for the program download is trustworthy.

Also, choosing Advanced or Custom installation options can help you with the secure download and installation too. Selecting such an option, you can see the full list with included programs and decide which ones to install and which ones are not wanted.

How to remove OberonBooster

Nothing it reports is real.

These steps remove it and undo a payment if you made one.

  1. Step 1: Do not pay, and undo a payment if you made one

    Nothing that OberonBooster says it found needs fixing by OberonBooster. Close its windows and do not enter card details.

    If you bought it, contact your bank or card issuer about a dispute and cancel any renewal, keeping the receipt e-mail as evidence. Uninstalling it from Windows 11 or Windows 10 removes the program but leaves the subscription running.

  2. Step 2: Uninstall OberonBooster

    OberonBooster is removed like any other program, from the list of installed apps. In Windows 11 that is Settings > Apps > Installed apps, in Windows 10 Settings > Apps > Apps & features, and in both you can also use Control Panel > Programs and Features.

    Select OberonBooster, click Uninstall and follow the uninstaller to the end. Then look at the entries just above and below it when the list is sorted by date: bundled programs install at the same minute.

  3. Step 3: Remove it from startup

    Press Ctrl + Shift + Esc to open Task Manager and select Startup apps (Windows 11) or the Startup tab (Windows 10). Disable entries you do not recognise, especially ones with no publisher or with a name that copies a Windows component.

    Right-click an entry and choose Open file location to see where it runs from: programs in %AppData% or %Temp% deserve a closer look. Some entries are not listed there but in the registry Run keys, which the procedure below shows how to check.

    Full procedure with screenshots: Stop apps from opening at startup On uGetFix

  4. Step 4: Delete the folders left behind

    Uninstalling often leaves the program's folders, and some threats reinstall themselves from them.

    Press Windows + R, type %LocalAppData% and press Enter, then do the same for %AppData% and %ProgramData%, and look for folders named after OberonBooster, its publisher or created on the day the problem started. Delete those folders, and check C:\Program Files and C:\Program Files (x86) too.

    If Windows says a file is in use, end it in Task Manager or delete the folder after a restart in Safe Mode. The folders are the same in Windows 11 and Windows 10.

    Full procedure with screenshots: Remove what malware leaves behind in Windows

  5. Step 5: Scan the PC, then run the offline scan

    A scan finds the parts of OberonBooster that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.

    Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.

    It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.

    Windows Security Scan options with Microsoft Defender Antivirus offline scan selected
    Windows 11: Windows Security > Virus & threat protection > Scan options.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices.

Avoid any unwanted government tracking or spying by going totally anonymous on the internet.

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings.

Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact - you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use for the data restoration process.

Get rid of the program possibly related to additional intruders and fully uninstall OberonBooster PUA

Even though you shouldn't use the name of the OberonBooster virus in such a manner, this program can be considered a malware when it gets exceptionally difficult to remove from your device. Since the installation might happen without your permission or knowledge, there is no guarantee that during the process program hasn't planted some files in folders of the system.

OBERONBOOSTER removal should be quick and successful if you choose the needed program – anti-malware tool. This is how you can find all the silently added files, folders, or even additional applications. AV engines detect various suspicious activities and can remove programs, files that can be considered harmful.

When you remove OBERONBOOSTER from the system with such a program, you can see all the potential intruders too. Also, the procedure eliminates threats that you had no idea about. However, to improve the performance further - scan the machine using a PC repair utility and recover crucial functions of the machine.

Questions about OberonBooster

Can I safely uninstall OberonBooster?

If you did not install OberonBooster yourself and it is not part of your hardware or a program you rely on, yes. Uninstalling an unwanted program does not harm Windows. Before you do, search the exact name and publisher to be sure it is not a driver tool, a printer utility or a game launcher with an odd name.

Then remove it from Settings, Apps, Installed apps. Ignore any offers or warnings in its uninstaller about losing protection or performance. Afterwards check Startup apps and your browsers for leftovers, and restart once to confirm that it does not reinstall itself.

OberonBooster came back after I uninstalled it. Why?

Something else is reinstalling it. Common causes are a second program from the same publisher, a scheduled task that downloads it again, or a browser extension that keeps prompting for it. Sort Installed apps by install date and uninstall each entry from the same day that you did not choose.

Then open Task Scheduler and look in the Task Scheduler Library for tasks with updater-style names that you do not recognise. Check Startup apps in Task Manager too. If OberonBooster still returns, start Windows in Safe Mode, uninstall it there and run a Microsoft Defender offline scan, which looks for loaders that ordinary scans can miss.

Is my card safe after buying OberonBooster?

Treat it as exposed. The order page belongs to the seller of OberonBooster, and you cannot know how the number is stored or shared. Ask your bank for a replacement card, which is usually free, and dispute the original charge as a misrepresented product.

Until the new card arrives, check your account daily for small or foreign transactions. If the bank offers alerts for every card payment, turn them on. Keep the receipt and screenshots, because they support the dispute.

Is OberonBooster a real Windows warning?

No. Real Windows Security notifications appear in the notification area and in the Windows Security app, use Microsoft's design and never ask you to call a phone number or pay to fix anything. What people report is oberonBooster in the list of installed apps, drawn by a program that copies the look of a system message.

Open Windows Security from the Start menu to see the real status of your PC. If it shows no threats while the window keeps appearing, the window itself is the problem, and the plan in this guide removes the program that shows it.

Is OberonBooster an antivirus?

No. It looks like one, with a shield, a scan and a list of threats, but OberonBooster is a rogue antivirus: its scans are designed to find something every time, and every fix leads to a payment page.

A real antivirus detects the same threats consistently, removes them without asking for money first and does not block other security tools. Windows 11 and Windows 10 already include Microsoft Defender in Windows Security, which is enough for most home users. Remove OberonBooster and keep Defender on.

Is Windows Security enough to protect me from programs like OberonBooster?

For most home users, yes, especially with Potentially unwanted app blocking turned on in Windows Security > App & browser control > Reputation-based protection settings. That setting blocks many scareware installers before they run.

No security tool stops every scam, though, because programs like OberonBooster are usually installed by the user after a frightening message. The habit that helps most is simple: ignore any website or pop-up that claims to have scanned your PC, and never call a number shown in a warning.

What if I paid OberonBooster?

Contact your bank or card issuer the same day, explain that the payment went to a fake security program and ask for a chargeback. Keep screenshots of oberonBooster in the list of installed apps, the payment receipt and any e-mails.

If you gave card details in the program, ask the bank to block and replace the card. Then uninstall the program and run a full scan in Windows Security. If you also called a number and let someone connect to your PC, uninstall the remote-access tool they used and change your passwords from another device.

Do I need to reinstall Windows to get rid of OberonBooster?

Usually not. A thorough clean-up is enough when the offline scan finds nothing afterwards and you do not see oberonBooster in the list of installed apps again. A reset is the safer choice if an attacker had remote control, if security tools were switched off, or if detections come back after every clean-up.

Windows 11 can reset itself without a USB stick under Settings > System > Recovery > Reset this PC. Copy documents and photos out first and scan the copies. A reset does not change passwords or undo stolen data, so the account steps still apply.

OberonBooster will not uninstall. What can I do?

Close it in Task Manager first, then uninstall it from Settings > Apps > Installed apps (in Windows 10, Apps & features). If it blocks this or restarts itself, start Windows in Safe Mode, where third-party programs do not start automatically, and uninstall from there.

Afterwards run a Microsoft Defender offline scan and delete any leftover folder named after OberonBooster in C:\Program Files or %AppData%. If nothing works, Windows can be reset while keeping your personal files, which removes the program together with any settings it changed.

Will Fortect remove OberonBooster?

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For OberonBooster, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
