How OnrymSpeedup got on your PC
From our report of Oct 2026 · not reviewed since
Software bundling isn't a new thing.
App developers include additional installers with their creations to gain revenue from promotional software. Some of it may be useful, but in most cases, bundled software contains potentially unwanted programs.
The worse thing is that more and more software developers are offering software bundles. That's why people should be attentive when installing any new apps. Please don't ever choose the Recommended, Quick, or Standard installation modes as all programs are preselected for installation.
Take your time and pick the Custom or Advanced option. Only by choosing either of these modes will you be able to deselect untrustworthy, unnecessary apps from installing on your device. Also, all software offered in the bundle is listed in the EULA, so you can read all about it.
How to remove OnrymSpeedup
Nothing it reports is real.
These steps remove it and undo a payment if you made one.
Step 1: Do not pay, and undo a payment if you made one
Nothing that OnrymSpeedup says it found needs fixing by OnrymSpeedup. 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.

Step 2: Uninstall OnrymSpeedup
OnrymSpeedup 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 OnrymSpeedup, 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.

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
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 OnrymSpeedup, 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.

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

Questions about OnrymSpeedup
What is OnrymSpeedup and why is it on my PC?
OnrymSpeedup is a program that was installed on the PC, most likely together with something else you downloaded. Free software sites and many installers add extra programs on setup pages with pre-ticked boxes, so the extra install looks like your choice even though nobody read the page.
Check the install date in Settings, Apps, Installed apps: the program you installed that day is the probable carrier. If you do not need OnrymSpeedup, uninstall it. If it belongs to your hardware or to a program you use, search its exact name and publisher first, because drivers and their tools can have unfamiliar names.
OnrymSpeedup 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 OnrymSpeedup 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.
Do I need to reinstall Windows to get rid of OnrymSpeedup?
Usually not. A thorough clean-up is enough when the offline scan finds nothing afterwards and you do not see onrymSpeedup 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.
Is my card safe after buying OnrymSpeedup?
Treat it as exposed. The order page belongs to the seller of OnrymSpeedup, 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.
What could the caller do while connected to my PC?
Anything you could do. Callers working with fake alerts like OnrymSpeedup typically show you Windows logs as "proof", install their own remote tool for later, and steer you to online banking or a gift card purchase. Some add a password to Windows or lock the PC if you refuse to pay.
Remove every remote access program you did not install yourself, check Settings > Accounts > Other users for new accounts, and change important passwords from a clean device. If you cannot be sure what was changed, a reset of Windows is the safe choice.
I called the number from OnrymSpeedup. What now?
End the call and do not let them reconnect. If they installed a remote-access tool, disconnect the PC from the internet and uninstall that tool from Installed apps. Change passwords for e-mail, banking and anything you typed during the call, using another device.
If you paid, contact the bank today for a chargeback. Report the number to the authorities in your country. The program behind onrymSpeedup in the list of installed apps still needs removing: follow the plan in this guide, then run a full scan in Windows Security.
OnrymSpeedup 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 OnrymSpeedup 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.
How do I know OnrymSpeedup is fake?
Three things give it away. It appears as onrymSpeedup in the list of installed apps, a window from a program rather than from Windows Security. It pushes you to act quickly by calling, paying or downloading.
And the threats it reports never show up when you run a scan in the real Windows Security app. Microsoft does not put phone numbers in warnings or charge for removing threats through pop-ups. Close the window, do not call, and follow the steps to find and uninstall the program behind it.
Is Windows Security enough to protect me from programs like OnrymSpeedup?
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 OnrymSpeedup 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.
Will Fortect remove OnrymSpeedup?
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 OnrymSpeedup, 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.
