Quick Defragmenter - How To Remove?


Quick Defragmenter is a fake computer optimization program from malicious family of malwares known to be connecting Smart Defragmenter, HDD Defragmenter and another threats. Quick Defragmenter infection is propagated throughout the Internet – phony online virus scanners and exaggerated popup ads offer to install its unregistered version or even simply let Trojans inside the unprotected systems. Once installed, Quick Defragmenter appears to have the same GUI just like the previously mentioned scarewares (thanks foro S!Ri for a screenshot). Besides, its misleading campaign is also typical to these scams, so just after you notice it on your machine, it will make you start wondering how to get rid of Quick Defragmenter.

Quick Defragmenter does not ask for user his approval while infiltrating the PC. This unexpected intrusion is led by some modifications made to the Registry so that the compromised OS starts running malware’s executable each time the PC starts. When launched, Quick Defragmenter will issue a great number of invented problems and infections detected:

Requested registry access is not allowed. Registry defragmentation required

32% of HDD space is unreadable
Bad sectors on hard drive or damaged file allocation table

It will then advise you do install the ‘powerful’ software to solve this and that means that you will have to buy it at first. Additionally, Quick Defragmenter will make it difficult to run all your programs and instead of launching the application  it will display various security notifications, for example:

Windows cannot find ‘winword’. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

  1. I downloaded the malwarebytes program and scanned the computer. It found 22 infections. It removed them all, so it said and rebooted. The Quick Defrag thing isn’t coming up, but it’s still coming up with the error about disk drive restored. This happens every time I try to open a program. What should I do now?

  2. That is because malwarebytes has not cleaned everything out. Scan with Spyware Doctor to see what you got, or try searching for the files manually. You can also try scanning with alternate tools, like superantispyware, Hitman pro, etc.

  3. I did spyware doctor, but it really doesn’t do anything unless you buy it. Is there any free program out there that can fix it? It’s also saying something about not enough disk space or memory space, I can’t remember. This flashes up when the other warning flashes.

  4. Christie : Expand threats SD finds and delete the files found.
    You can also delete Quick defragmenter manually (instructions provided) but you might miss something like hidden trojan. Spyware Doctor is safer choice.
    you can try other tools : MBAM, Hitman pro.
