HDD Diagnostic is a rogue disk defragmenter which was first reported in December 2010. It is another name for Hard Drive Diagnostic and Win HDD, and it may intentionally mimic or copy rogue defragmenter application HDD Control. HDD Diagnostic is meant to con you into believing it to be a real system tool, when it is actually the basis for a scam and should be treated with suspicion.

Similarities to Other Rogues

HDD Diagnostic arrives on a computer by way of a Trojan Horse, which is typically picked up while you surf the Internet. Like its fellow fake system utility scams, HDD Diagnostic may find its way in as a fake browser add-on or extension, or a fake free system scan. The reality is, you probably will not know how it got there, but HDD Diagnostic is malicious and cannot be trusted.

The most notable symptom of an infection with HDD Diagnostic is its constant generation of "nag" messages. HDD Diagnostic will, once it has found a way in, create a perpetual flood of frightening warnings. Typically, the warnings will say that something has gone very wrong with some portion of your hard disk, like that some piece of data can't be written or accessed, or that there has been a critical error with the hard disk. HDD Diagnostic may even prevent other applications and Task Manger from running, and will instead give an error message that there was a critical failure in reading the hard disk. Then, as you might expect, HDD Diagnostic offers a "solution," which is that you can buy the premium version of its software in order to fix your supposed problems. Do not pay money for this bogus software, because it is completely fake and will not do anything to benefit your system.

A Word of Caution

There have been claims that HDD Diagnostic is relatively difficult to remove compared to other viruses. This is because HDD Diagnostic cannot be uninstalled, and it is supported by rootkits and other adware. It is best to proceed with caution in removing HDD Diagnostic, but it can and should be safely handled.
