How to remove System Defragmenter (Uninstall Guide)

System Defragmenter is a fake defragmentation and system optimization program that deliberately reports non-existent hard drive errors, junk files, Windows registry errors, missing or outdated drivers and other fake problems on your computer. It only pretends to scan your hard drive for problems. It simply lists predetermined errors and that's all. It should be noted that System Defragmenter reports basically the same fake errors on different computers, so obviously you shouldn’t trust it. After the fake scan, you will be prompted to pay for a full version of the program to fix these non-existent hard drive and registry errors. It goes without saying that you shouldn’t purchase System Defragmenter. Don't throw your money away. It does not worth a dime. If you are reading this article then your computer is probably infected with System Defragmenter. Thankfully, we've got the removal instructions to help you to remove System Defragmenter from your computer for free using legitimate anti-malware software. Please follow the removal instructions below.

Probably the most annoying thing about SystemDefragmenter is that this program blocks nearly all executables on your computer. When you attempt to run any of them it will claim that Exe file is corrupted and display the following message:

System Error!
Exe file is corrupted and can't be run. Hard drive scan required.
Scan Hard Drive

However, if you attempt to run a program enough times it will eventually work. But that's very annoying. Furthermore, the fake program will display many fake error messages and pop-ups from the Windows taskbar. It may claim that RAM temperature is critically high and that there are many critical hard drive and registry errors that should be fixed immediately. Here's a list of the fake problems it detects on your computer:

Drive C initializing error
Bad sectors on hard drive or damaged file allocation table - Critical Error
Read time of hard drive clusters less than 500 ms - Critical Error
Hard drive does not respond to system commands - Critical Error
Requested registry access is not allowed. Registry defragmentation required
Registry Error - Critical Error

And here's a list of some of the fake alerts you may see coming from the Windows taskbar:

Critical Error
RAM memory usage is critically high. RAM memory failure.

Critical Error
Windows can't find hard disk space. Hard drive error

Critical Error
Hard Drive not found. Missing hard drive.

System Defragmenter
Restart in Safe Mode required
Restart the computer in Safe Mode to fix detected problems
Restart your computer in Safe Mode, and then run
the Defragmenter tool. Starting Defragmenter in Safe Mode
help to prevent system damage and data loss. Please
do not start other applications until the process has complited

Of course, there are more such fake alerts. System Defragmenter is promoted through the use of fake online scanners and bogus/infected web pages. It's not a legitimate program and it doesn't allow you to use your computer properly. Without a doubt, you should remove System Defragmenter from your computer as soon as possible. Please don't purchase. If you have already bought this malware then contact your credit card company and dispute the charges. Then please follow System Defragmenter removal instructions given below. You can remove it either manually or using free legitimate anti-malware software. Last, but not least, if you have any questions or additional information about the rogue program, please leave a comment. Good luck and be safe online!
