Total PC Defender is a fake antivirus program that claims to offer proper functionalities
Total PC Defender is the rogue program is from the same family as other tools focusing on deceptive techniques.
More generally speaking, it's nothing more but a typical unwanted application that displays misleading security alerts and reports false system security threats to make you think that your computer is infected with Trojans, worms, and other malicious software.
When running, it will imitate a system scan and display numerous infections. Of course, scan results are false. Then it will ask you to pay for a full version of the program in order to remove the infections which actually do not even exist.
What is more, Total PC Defender will constantly display fake security alerts stating that your computer is under attack or seriously infected. It will also claim that malicious programs that may steal your private information were detected. The fake notification states:
There are more fake warnings and you will likely see all of them if your computer is already infected. However, false scan results and fake security alerts are not the biggest problems. The most annoying thing is that Total PC Defender blocks particular software and disables important system tools or options.
It can disable system restore and block safe mode too. In some cases it will block all executable (.exe) files, so you won't be able to launch any anti-spyware software or malware removal tool. Try to download and run an automatic removal tool like or .
First of all, you have to end the main process of Total PC Defender which is Total PC Defender.exe. Use Task Manager. Please note that there might be more active malicious processes generated by the PUP. There are various startup and registry entries, so run to take care of these issues.

How to remove Total PC Defender
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
Total PC Defender reports problems to sell a licence: the "threats" or "errors" it lists are invented or harmless leftovers. If you already paid, ask your card issuer to dispute the charge and cancel the subscription both in the seller's account and through your bank.
If you called a phone number it showed and let someone connect, treat the PC as remotely accessed and remove the remote tool. Uninstalling it from Windows 11 or Windows 10 does not cancel a subscription by itself.

Step 2: Uninstall programs you did not mean to install
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10, and sort the list by install date. Look at what appeared around the day the problem started and uninstall every program you do not recognise or did not choose.
Free converters, PDF and video tools, "system optimizers" and unknown browsers are the usual carriers of Total PC Defender. If a name is unclear, search for it before you remove it, so you do not uninstall a driver or a Windows component.

Step 3: Remove it from startup
Whatever Total PC Defender 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 4: 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 5: 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.

Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online.
One of the basic means to add a layer of security - choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features.
However, if you want true anonymity, we suggest you employ a powerful VPN - it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable.
Family photos, work documents, school projects - these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur:
- power cuts
- Blue Screen of Death errors
- hardware failures
- crypto-malware attack
- even accidental deletion
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, can be your only hope to retrieve your invaluable files.

Questions about Total PC Defender
What is Defender.exe and why is it running?
Every process is started by something:
- a program you installed
- a Windows service
- a scheduled task
- a startup entry
To learn why Defender.exe runs, find its file with Open file location in Task Manager, then look for an entry pointing to that file in Settings > Apps > Startup and in Task Scheduler.
Sort Installed apps by date to see what arrived when the process first appeared. Once you know the owner, you can decide whether to keep it, switch it off at startup or uninstall it completely.
Defender.exe keeps coming back. What should I do?
A process that returns after you end it has a restart mechanism, and that is a reason to treat Defender.exe as unwanted. Check Settings > Apps > Startup, Task Scheduler and the Services list for entries pointing to its folder, and disable them.
Look in Installed apps for anything added the same day and uninstall it. Then delete the folder and run a Microsoft Defender Offline scan, which works before Windows starts and can remove files that are locked or hidden while the system is running.
I called the number from Total PC Defender. 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 an unfamiliar process called Defender.exe in Task Manager still needs removing: follow the plan in this guide, then run a full scan in Windows Security.
Do I need to buy antivirus after removing Total PC Defender?
No. Windows 11 and Windows 10 include Microsoft Defender in Windows Security, which provides real-time protection, scheduled scans, the offline scan and protection against unwanted apps at no cost. Keep it switched on and updated, and turn on Reputation-based protection under App & browser control.
If you prefer a third-party product, buy it from the vendor's own site after reading independent test results, never from a pop-up or a phone call. The lesson of Total PC Defender is that security offers which arrive unasked are the ones to avoid.
How do I know Total PC Defender is fake?
Three things give it away. It appears as an unfamiliar process called Defender.exe in Task Manager, 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.
Should I reset my PC because of Total PC Defender?
Only if the signs point to deeper access. Reset when you see an unfamiliar process called Defender.exe in Task Manager again after removal, when Windows Security cannot start or update, when remote access tools you did not install keep appearing, or when you simply cannot trust the PC any more.
Otherwise, the plan in this guide plus an offline scan is enough. If you do reset, choose Remove everything and Cloud download for a fresh copy of Windows, restore only documents and photos, and reinstall programs from their official sites. Change important passwords from the clean system afterwards.
I let a technician connect to my PC because of Total PC Defender. Is it safe now?
Not until you check. While connected, the caller could install other programs, create a user account or look at saved passwords. Disconnect from the internet, uninstall the remote access program and anything else installed during the call, and run a full scan and the Microsoft Defender offline scan.
From another device, change your e-mail and banking passwords and turn on two-step verification. If the caller opened your online banking, call the bank today. A reset of Windows is the safest option if you cannot tell what was done.
What should I do if I already clicked or replied to Total PC Defender?
Stop all contact, do not click anything else and secure your accounts right away. If you typed a password, change it at once from a clean device, then turn on two-factor authentication.
If you gave card or bank details, call the bank on the number printed on your card and ask to block or replace it. If you installed something or allowed remote access, disconnect from the internet and follow the removal plan. Keep screenshots and the message, because they help when you report it.
Will Fortect remove Total PC Defender?
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 Total PC Defender, 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.
