Disk OK and HDD OK are the names of basically the same piece of malware that poses as the Windows disk defragmenter utility. The rogue program proceeds to scan your computer, finds eleven critical errors and gives you two options; purchase advanced module license to fix the problems or to stay unprotected. If you choose to stay unprotected it will display disturbing hard drive errors messages and block other programs so that you will not be able to use them properly. Disk OK is very annoying scareware. It not only gives you a false sense of system status and performance but also interrupts your work.
