Windows Expansion System is a rogue anti-spyware application that displays fake error messages and security alerts to trick users into buying the full version of the program to remove the infections or fix the errors. These alerts may be pop-up windows from your Windows task bar that state active infections have been found or that your computer is under attack. It is promoted through the use of Trojans that usually come from fake online scanners and infected websites. Once installed Windows Expansion System will be configured to start automatically when you login to Windows. It will scan the system and then state that there are many infections on your computer. This rogue application will not allow you to remove any of supposedly found infection until you purchase the program. You should ignore what this program displays and remove Windows Expansion System from your computer as soon as possible.

Please ignore these fake security alerts as they were created to make you think that your computer is infected when in reality, the only infection infection on your computer is Windows Expansion System. You can remove the rogue program manually, but it may come bundled with other malicious software, rootkits, trojans that can install additional malware onto your computer. We strongly recommend you to use an automatic removal tool given below to remove Windows Expansion System and additional viruses from your computer. Windows Expansion System is not a program that you want on your computer or that you should trust what it says.
