XJR Antivirus: what it is and how to remove it

It depends on where the file is and who signed it, not on the name. Open Task Manager, go to the Details tab, right-click Antivirus.exe and choose Open file location. A file inside Program Files or System32 with a valid digital signature from a known company is usually part of a legitimate program.

A file in AppData, Temp or ProgramData with no signature, especially one that restarts itself after you end it, is suspicious. If you cannot tie the process to anything you installed, uninstall recent unfamiliar programs and run a Microsoft Defender Offline scan.

Only after you know what it belongs to. If Antivirus.exe is part of a program, uninstall that program through Settings instead, so its services and tasks go too. If it belongs to nothing and is unsigned, end the process, disable whatever starts it and then delete its folder.

Do not delete files from the Windows folder or files signed by Microsoft: those are part of the system, and removing them can stop Windows from starting. When in doubt, run a Microsoft Defender scan first and let it decide.

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 Antivirus.exe in Task Manager still needs removing: follow the plan in this guide, then run a full scan in Windows Security.

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.

Only if the signs point to deeper access. Reset when you see an unfamiliar process called Antivirus.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.

Because copying the design costs nothing and makes people trust it. The program behind an unfamiliar process called Antivirus.exe in Task Manager borrows Windows colours, icons and wording, sometimes even the name of a well-known security brand. None of that gives it access to real security information.

A real alert can be checked in seconds: open Windows Security from the Start menu and look at Protection history. If nothing is listed there, the official-looking window is fake, and the program that draws it is what needs to be removed.

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 XJR Antivirus is that security offers which arrive unasked are the ones to avoid.

XJR Antivirus is a rogue anti-spyware program that displays fake security alerts and reports false infections to scare you into thinking that your computer is infected with spyware, adware and other malware. The rogue program is a clone of Your PC Protector scareware and it is promoted mostly through the use of Trojans and fake online anti-malware scanners.

The summary table at the top of this guide lists the type, the detection names, the symptoms and the damage of XJR Antivirus. Reading it first helps you decide whether your computer shows the same signs.

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 XJR Antivirus, 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.
