Here you will be able to take full control of all incoming objects and deselect any product that looks questionable to you. However, the best thing to do here would be to download products and services only from their original developers.

How to uninstall Bestantius.com
How to remove Bestantius.com
Uninstall the bundle first, then everything it added:
- programs
- extensions
- changed browser settings
Step 1: Uninstall Bestantius.com
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10. Sort the list by install date and find Bestantius.com, then choose Uninstall from the three-dot menu next to it (in Windows 10, click the entry and then Uninstall).
Remove anything else installed on the same day that you do not recognise, because such programs usually arrive together in one installer. If the uninstaller opens a browser page with an offer or a survey, close it: the program is removed either way.

Step 2: Remove it from startup
Whatever Bestantius.com installed usually starts with Windows. Open Task Manager with Ctrl + Shift + Esc, go to Startup apps in Windows 11 or the Startup tab in Windows 10, and disable what you do not know, starting with entries that have an empty Publisher column.
Open file location on the right-click menu shows the file, which helps you decide and tells you what to delete later. Disabling is safe: if something you need stops working, switch it back on.

Step 3: Delete the folders left behind
What the uninstaller leaves behind is usually in the user folders. Open File Explorer, switch on View > Show > Hidden items (in Windows 10 View > Hidden items), and go through
%LocalAppData%,%AppData%, %ProgramData% and the two Program Files folders.Sort by Date modified and delete folders that appeared together with the problem and belong to no program you use. Folders with random names that hold
.exe,.dll, .js or .ps1 files are the strongest sign.Full procedure with screenshots: Remove what malware leaves behind in Windows
Step 4: Scan the PC, then run the offline scan
Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.
Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.

Questions about Bestantius.com
What is Bestantius.com and why is it on my PC?
Bestantius.com 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 Bestantius.com, 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.
Bestantius.com will not uninstall. What can I do?
First restart the PC and try again, because the program may have been running and locked its own files. If the uninstaller is missing or fails, start Windows in Safe Mode, where most third-party programs do not start, and remove Bestantius.com from Installed apps there.
If it still refuses, delete its startup entry and its scheduled task, restart, and try once more. A program that actively prevents removal is behaving like malware, so finish with a Microsoft Defender offline scan. Avoid third-party uninstallers offered on search ads; several of them are unwanted programs themselves.
Does Bestantius.com use a lot of resources?
It depends on the program, and no measurements have been published for Bestantius.com. The sign reported is bestantius.com in the list of installed apps. Check for yourself: open Task Manager, find its process and watch the CPU, memory and network columns for a minute while the PC is otherwise idle.
Steady use with nothing open is a strong reason to remove it. Even if it seems light, it may run more processes under other names, so sort Installed apps by date and remove anything else from the same day. Then restart and compare.
Does Bestantius.com collect my data?
Nobody has analysed Bestantius.com yet, so there is no confirmed answer. Programs in this category often collect usage data, browsing history or device details and share them with advertisers, and their privacy policies usually allow it.
The sign reported, bestantius.com in the list of installed apps, does not by itself show data theft, and nothing points to passwords or files being taken.
If you want to be careful, clear the browser's cookies after removal and review which apps may run in the background. Change passwords only if you also see signs of something more serious, such as unknown sign-ins or messages sent from your accounts.
Why does my antivirus call Bestantius.com a PUA or PUP?
These labels mean potentially unwanted application or program. They are used for software that is legal but uses deceptive distribution, aggressive ads, misleading claims or a hard removal. Microsoft's PUA categories include advertising software, bundlers, download managers, torrent clients, marketing software and miners.
A PUA detection is a warning, not proof of infection, and you decide whether to keep Bestantius.com. Other vendors use their own labels for the same idea, such as PUP.Optional or not-a-virus. Read more in our guide to potentially unwanted programs.
Why can't I uninstall Bestantius.com?
Usually because it is still running or because a helper reinstalls it. Close it from the notification area first, then end its process in Task Manager and try Settings > Apps > Installed apps again. If there is no uninstall entry, look for a folder under Program Files or AppData with the same name and an uninstaller inside.
If the program comes back after removal, the cause of bestantius.com in the list of installed apps is a scheduled task, a startup entry or the program it was bundled with. Remove those, restart and check again. Starting Windows in Safe Mode stops most helpers and makes stubborn programs easier to remove.
Can Windows block unwanted programs automatically?
Yes, with one setting. Windows Security has Potentially unwanted app blocking under App & browser control > Reputation-based protection settings. Block apps stops flagged programs from installing, and Block downloads works in Microsoft Edge.
On some PCs this was not switched on, which is how programs like Bestantius.com got through. It does not catch everything, so read installer screens, choose Custom setup and decline offers. Removing free tools you no longer use also helps, because their updates are a common route for new bundles.
Can I use Bestantius.com safely?
Yes, if you installed it on purpose and control its settings. Download it only from the publisher's own site, never through a bundle or a portal. After installing, disable automatic start, offers and telemetry, and check that it did not change your search engine or add extensions.
Watch for renewals if you bought a licence, and turn on PUA blocking in Windows Security so that anything it tries to add during updates is stopped. If Bestantius.com keeps pushing payments or offers, it is not worth the trouble.
How do I know if I need Bestantius.com?
Ask three questions. Did you install it on purpose? Have you ever opened it?
Does anything you use depend on it? If the answers are no, you do not need it. The sign that brought you here, bestantius.com in the list of installed apps, suggests it arrived without a clear choice.
Programs bundled with free software rarely do anything their host program needs. Uninstall it, restart, and see whether anything you rely on stops working. If nothing does, which is the usual outcome, you can forget about it.
Will Fortect remove Bestantius.com?
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 Bestantius.com, 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.
