Fast Disk is a rogue defrag utility that displays convincing hard drive and system error messages to make you think that your computer has some serious stability and performance problems. It reports non-existent performance issues, critical hard drive and Windows registry errors and some other problems. Basically it's just another Trojan that looks legitimate and tries to steal money from inexperienced Internet users. Fast Disk malware is distributed through poisoned search results and fake online scanners as a codec or flash player that is required to view online videos. Fast Disk or a trojan downloader can also masquerade as malware removal tool, e.g. Windows Defender. If you somehow ended up with this scareware, please do not pay for simulated removal of malware or other computer problems. Fast Disk will state that you need to install advanced module to fix certain hard drive and system errors. Do not fall victim to this scam. Instead, please follow the removal instructions below to remove Fast Disk malware from your computer.
Once the rogue program is installed, it will display a fake Fix Disk Windows diagnostic utility which will supposedly check hard drive sectors and registry integrity.
After the fake scan it will prompt you to run Fast Disk malware in order to fix computer errors. Fast Disk will perform another fake system scan and display eleven computer errors. It will pretend to fix six errors. If you want to fix the remaining errors you need to buy the "advanced module". Furthermore, Fast Disk will block other programs on your computer saying that there is a critical hard drive error which prevents the execution of certain applications and system utilities.
Critical Error
Damaged hard drive clusters detected. Private data is at risk.
To make things even worse, Fast Disk will change your desktop background and hide all desktop icons. Here are some of the fake warnings that you may see if you have this rogue program on your computer:
