System Defragmenter is a noxious program that imitates a computer optimization tool that scans computer system and detects disc problems. This rogue application is installed to random computers through malware infections and uses typical methods in order to trick computer users and rip them off by selling a fake program.
Right when System Defragmenter is downloaded and installed to computer, it is enabled to be run each time Windows is started. As a consequence, you will experience tons of unwanted actions on your system, such as displaying fake alerts that warn about hardware failure, etc. The warnings read:
Hard Drive not found. Missing hard drive.
RAM memory usage is critically high. RAM memory failure.
Windows can’t find hard disk space. Hard drive error
Damaged hard drive clusters detected. Private data is at risk.
Windows was unable to save all the data for the file \System32\496A8300. The data has been lost. This error may be caused by a failure of your computer hardware.
A critical error has occurred while indexing data stored on hard drive. System restart required.
The system has been restored after a critical error. Data integrity and hard drive integrity verification required.
While trying to launch any executables, System Defragmenter will block the action and instead it will generate another message:
Exe file is corrupted and can’t be run. Hard drive scan required.
Scan Hard Drive
System Defragmenter also pretends to scan infected computer system and reports about some disc errors which in fact are absolutely fake. However, the program will attempt to convince you to find a bunch of problems on your system. Here are a few examples of the messages you can receive after System Defragmenter finishes its scan:
Read time of hard drive clusters less than 500 ms
32% of HDD space is unreadable
Hard drive does not respond to system commands
Bad sectors on hard drive or damaged file allocation table
Drive C initializing error
Ram Temperature is 83 C. Optimization is required for normal operation.
Data Safety Problem. System integrity is at risk.
Requested registry access is not allowed. Registry defragmentation required
Registry Error – Critical Error
GPU RAM temperature is critically high. Urgent RAM memory optimization is required to prevent system crash
Do not take these notifications for granted under any circumstances as SystemDefragmenter doesn’t have any properties of a legitimate optimization tool. You are strongly adviced to remove System Defragmenter as soon as possible instead of trusting any information it provides.
For temporal, disable System Defragmenter popups with key 0973467457475070215340537432225 . For full removal, a scan with Malwarebytes Anti-Malware or spyhunter is required. I recommend upgrading the software to full version for protection from similar parasites.
