How to Remove Windows Diagnostic Virus



The Windows Diagnostic virus typically is commonly disguised as a diagnostic tool that concentrates on detecting and fixing any hard drive and system errors discovered on your personal computer. 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. These websites will launch a phony analysis and generate reports of several hard disk and system problems. 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.
