If you somehow ended up with this rogue program then you probably already know how annoying it can be. The biggest problem with Smart Defragmenter is that it blocks any executables on your computer as claims that they are corrupted. It displays a fake error message with the following text:
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. What is more, Smart Defragmenter will display many fake errors and warnings from your Windows Taskbar. It will claim that your hard drive is missing. That's actually ridiculous. It can't just disappear. Then it will state that the system has been restored after a critical error and that about half of your HDD space is unreadable. Don't fall victim to this rogue program. All these problems are fake. The text of some of the alerts you may see include:
Critical Error!
Damaged hard drive clusters detected. Private data is at risk.
Critical Error
Hard Drive not found. Missing hard drive.
Critical ErrorSome other fake problems read:
RAM memory usage is critically high. RAM memory failure.
Registry Error - Critical ErrorYou will probably see even more such fake alerts and computer errors while Smart Defragmenter is running on your computer. As you can see, this program is absolutely needless, so how to remove it from the system? First of all, you need to delete all files from the Windows Temp folder because the rogue program stores its files there. Then you should download free anti-malware program and scan your computer.
