Have used the Hitman site. Downloaded the kickstart to USB from clean computer. Followed directions on starting infected system, HP 4530s. Found several malware issues and quarantined them. Rebooted and same FBI screen comes up. Re-ran the kickstart and it indicates nothing found. Have attempted the safe mode and safe mode with networking, only to have system force restart and return to FBI screen. Have attempted to recover to a prior date and it indicates that the recovery is not on and the system will not allow to choose on.
