How to remove OneUpdater (Virus Removal Guide)


This page provides instructions to remove OneUpdater and other threats from your computer including viruses and malware.

What is OneUpdater?

OneUpdater (also searched for as OneUpdater virus) is a fake system utility tool for Microsoft Windows that is detected in several computer infection categories including malware, adware, and the potentially unwanted program (PUP/PUA) category.


OneUpdater may be difficult to locate on a computer. Executable icons and shortcuts may be located on Windows desktop, Windows taskbar, and in the start menu; However, when the shortcuts are activated nothing visually occurs. This is because the malware will only appear in the taskbar tray and will periodically show pop-up notification messages from the taskbar.

When the potentially unwanted program is installed it will create a task to run every time Windows starts and when Windows starts the program will automatically scan the computer. This can use a large number of system resources which can lead to problems with the integrity of the computer system.

How did OneUpdater get on my computer?

The malware may trick users into installing it by utilizing unethical marketing practices to promote itself across numerous websites and during the installation process of free programs. When installing free programs it is always advised to use caution and uncheck custom or advanced installation methods to avoid installing programs you want to avoid. In addition, advertisements that promote the program may be deceptive and misleading. Advertisements may promote the program as something it is not such as a flash player update to dupe internet users into installing the malware and other threats.
