Scandisk or Scandisk Defragger is another version of rogue system defragmenters. Though it uses a name of a well-known utility that cheks and repairs file systems or bad clusters on the hard drive, this fake system defragmenter has nothing in common with a legitimate program. Distributed by trojans in infected websites, it attacks infected PCs with various popups or alerts. The alerts state, that the PC hardware is in a very bad state: Hard disk is barely working with lots of bad sectors, ram is overheating, files cannot be accessed and so on. If you wonder why your sytem is so corrupt, the answer is simple: Scandisk is trying to sell itself, a corrupt system optimization program for 80 USDs or so.
All the warnings of Scan Disk Defragger are faked. No, there is nothing wrong with hardware of your system, but there are security holes that allow trojans infecting your PC and causing havoc. Even if you can not access some files due to some sort of HDD malfunction, they are still there and safe (for the moment). You should be able to launch most of executables after several tries. If you can’t access some website on first try, disable proxy server in your browser and it might open. do not pay attention to the blocking screens in Internet explorer that talk about network problems.
However, Scandisk rogue is annoying and should be removed, in many cases with trojan downloaders that infected your PC with it and might download other fake system utilities or fake antiviruses in the future.
Scandisk removal special instructions:
Scandisk, like similar rogues, install in temporally folders of your hard drive. Emptying all of them is the first step after killing its process or rebooting in safe mode with networking. I recommend utility CCleaner for that. Afterwards, search thoroughly for numerically named executables in C:\Users… or C:\Documents and settings\ in case you have missed something. Delete (or rename) them and that should disable Scandisk for good. I strongly recommend scanning with spyhunter or Malwarebytes to remove underlying problem: trojan downloaders, that might have been installed in different locations. I would suggest upgrading your antivirus and antispyware programs as well to avoid infections like Scandisk in the future.
