What Antivirus System Pro is
Antivirus System Pro is classified as a rogue anti-spyware application because it uses misleading methods in order to scare you into purchasing this program.
Usually, the rogue uses false scan results and fake security warnings. It states that your computer is infected with Trojans, adware or malware and that you should purchase Antivirus System Pro to remove these infections. Of course, these infections are all fake and don't actually exist on your computer. This parasite is advertised through the use of Trojans, such as notorious Zlob or Vundo.
It might be also promoted on various malicious websites. It will also flood your computer with very annoying pop-ups and security alerts. Here's an example of a fake Antivirus System Pro alert: "Windows Security alert Windows reports that computer is infected. Antivirus software helps to protect your computer against viruses and other security threats.
Your system might be at risk now." Obviously, these alerts are also fake. If your computer is infected with Antivirus System Pro, please use the removal guide shown below to remove it immediately. Removal delay will only worsen the situation, because Antivirus System Pro will download even more malware onto your computer.
How to remove Antivirus System Pro
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 Antivirus System Pro says it found needs fixing by Antivirus System Pro. 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 Antivirus System Pro
Antivirus System Pro 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 Antivirus System Pro, 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.

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
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 Antivirus System Pro, its publisher or created on the day the problem started.Delete those folders, and check
C:\Program FilesandC:\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
A scan finds the parts of Antivirus System Pro 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.

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.
Questions about Antivirus System Pro
Can I safely uninstall Antivirus System Pro?
If you did not install Antivirus System Pro 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.
How do I stop programs like Antivirus System Pro from being installed again?
Most unwanted programs arrive through installers, so the fix is in how you install software. Download programs from their official sites or the Microsoft Store, not from download portals or ads above search results. During setup, choose Custom or Advanced installation and untick every extra offer, including browsers, toolbars and optimizers.
Decline update prompts that appear inside other programs unless you know them. In Windows Security, turn on reputation-based protection and potentially unwanted app blocking. These steps would most likely have stopped Antivirus System Pro before it reached the app list.
Do I need to reinstall Windows to get rid of Antivirus System Pro?
Usually not. A thorough clean-up is enough when the offline scan finds nothing afterwards and you do not see antivirus System Pro 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.
What could the caller do while connected to my PC?
Anything you could do. Callers working with fake alerts like Antivirus System Pro 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.
Is Antivirus System Pro 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 antivirus System Pro 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.
Someone called offering a refund for Antivirus System Pro. Is it genuine?
Almost certainly not. Refund calls are a well-known second stage of scareware and tech support scams. The caller says you are owed money, asks you to install a remote access program to "process" it, then opens your online banking, makes it look as if too much was refunded and asks you to send the difference back.
Hang up. Real refunds go back to the card or PayPal account you paid with, through your bank or the payment provider, and never need remote access or a gift card.
Antivirus System Pro 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 Antivirus System Pro 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.
Is my card safe after buying Antivirus System Pro?
Treat it as exposed. The order page belongs to the seller of Antivirus System Pro, 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.
Did Antivirus System Pro steal my information?
Not by itself, as far as reports show. Programs that display antivirus System Pro in the list of installed apps are built to scare people into paying or calling; they rarely take data on their own.
The risk comes from what you did in response: typing card details into the program, or letting a caller connect to your PC. If you did neither, uninstalling the program is enough. If you did either, treat that information as exposed:
- block the card
- change passwords from another device
- remove any remote-access tool that was installed
Will Fortect remove Antivirus System Pro?
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 Antivirus System Pro, 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.
