System Defragmenter
System Defragmenter is a rogue program that disguises as another Windows security tool offering Hard Disk Drive Defrag and Repair, Disk Cleaner and Disk Scanner. Computer currently in possession of System Defragmenter is at risks and requires immediate attention. This malicious application was accompanied by a Trojan that will bypass security configurations and install unwanted programs on victims computer without users approval. Once loaded into the computer, System Defragmenter will display a “PC Performance & Stability analysis report” containing false and disturbing results. Some applications on the computer will be prevented to run stating that errors were encountered when running them. In the end, it will prompt users to get the System Defragmenter registered version to be able to bring back the PC to its original working state.
Instead of paying for this useless product, we suggest to invest your money on purchasing a good anti-malware solution. This legitimate program can take care of any virus and malware present on the computer. Most of all, it can help you remove System Defragmenter and stop all annoyances it has brought to the system.

NORTON 360 WILL REMOVE THIS VIRUS! I found myself overwhelmed with the manual removal instructions so I went to the Norton website and downloaded Norton 360 which is free for 90 days. I was pretty pessimistic about the outcome, I had run Avast and Malwarebytes with no luck. To my surprise after I scanned my computer and rebooted this ugly beast was gone!

My computer (which has Windows 7 installed on it) was infected with the system defragmenter a few days ago. I managed to uninstall it with the malwarebytes anti-malware download, but while I was doing this I noticed the virus has evolved from what most of the websites on how to fight the virus suggest. The system defragmenter now poses as ‘Windows Recovery’ and looks more professional and believable than the previous fake system defragmenter window of the older version of the virus. Also, trying to download known software to fight the virus does not tend to work as the virus, if it recognises the name of said software, will automatically delete it before you can get it to run. Clicking ‘OK’ to one of the fake error messages that also appears will cause your computer to reboot. In order to combat this, ignore the error messages and open the task manager, and go to the ‘Processes’ tab. End every process which is composed of seemingly random characters, or anything that looks suspicious. This will prevent the virus fro, deleting the antivirus software, and so you can then download the software and, running a full scan, identify and destroy the virus. However, even after the virus is gone, you will find it has wrought much damage. While it may seem that all your documents have been wiped, don’t despair; the virus has simply hidden then, so by going to the control panel and revealing hidden files and folders, you will find all of your documents still remain. You may also find some documents and folders have been moved to the recycle bin. However, if you look at the start menu, all of your programme files will be empty, as will the Program Files folder in (My) Computer. For me, MS Word and iTunes still worked, but all other programmes files had been renamed and moved to the ‘Windows’ folder, and then some applications (such as Paint) would not work. To combat this, I simply did a system restore (to do this, type in system restore at the search box at the bottom of the start menu) and restored the computer to the state it was in a few days before I got the virus. When my computer rebooted after the system restore, everything was back in it’s correct place, and it was like the virus has never happened.
Just something to be aware of if your computer has the System Defragmenter virus on a Windows 7 PC, or has had it and your files seem to be missing.
