Windows Diagnostic

With all the sophistication invested in the development of rogue defragmenter tools, it can be difficult to distinguish between genuine defraggers and harmful, rogue applications such as the malicious Windows Diagnostic. This rogue in particular is nothing more than a seditious application designed to act as a vessel for unscrupulous criminals to rip honest consumers off. This rogue will try everything in its power to come across as a genuine application, but at the end of the day Windows Diagnostic, which emanates from the same despicable family of rogues as Fake HDD and Windows Tool, does not have the abilities it professes to and will be the cause of much more problems to your PC than it will any good.

Windows Diagnostic enters the system surreptitiously through using seditious Trojans. These Trojans are distributed via fake online malware scanners and annoying browser hijacking web domains. Windows Diagnostic has also been known to bundle its Trojans and malware with other genuine security updates and downloads obtained from third party websites.

Because Windows Diagnostic’s infiltration of the PC is virtually undetectable by the user, he will have a lot of trouble to get rid of Windows Diagnostic without help. The first clue the user will have as to the presence of this rogue on his system will come from being spammed by various fake system notifications. These false alerts were designed to panic the user into thinking his system is operating less than optimally. The truth is all of the alerts are fake and falsely generated by Windows Diagnostic in an effort to force the user into paying for worthless software. Do not pay any attention to it, and be on the lookout for the following fake alerts:

    part of the affect this had was I was unable to connect to the internet. fortunately, i had an older laptop I could connect and check this very strange newly arrived windows diagnostics.
    I was unable to save the entire file to a usb drive to be able to use on the other computer.
    I would have paid alot for that - as I've already wated 5 hours today with a computer that just keeps rebooting and aren't progressing very far.
    thanks

    Sam Taylor,

    What do You mean by "I was unable to save the entire file to a usb drive"
    The installation file is only 1 MB size. It should definitely fit in any USB drive.
