Salut, I've tested the about.exe and it was Data Recovery aka Master Utilities. This rogue will disable your Taskmanager, hide all files + your hard drive. You can do nothing. If you're infected with Data Recovery or Master Utilities, please use this key to disinfect your PC. Serial = 1203978628012489708290478989147 The file will be dropped here: C:\Documents and Settings\All Users\Application Data\6DSS92c31Apgjk.exe After the registration you can download the registered copy of Master Utilities. Start a Quick Scan with Malwarebytes' Anti-Malware to delete the rest of files (Be sure your MBAM is updated!) Some screenshots:
