How to Remove Windows Diagnostic Virus

From the same group that developed the Windows Tool, this new rogue program was created specifically to earn income from online scams.

Usually, this rogue application will be distributed with a Trojan horse that will change Internet browsers on the compromised computer and redirect the user to malicious web sites.

At this moment a prompt to download and install a copy of Windows Diagnostic is displayed on your screen. Unknown to users, it is only an unregistered version and later on the software will compel victims to purchase the licensed version of the software.
