Sorry - I meant to post this thread here, but put it in a different place to start:
I have a version of the FBI ransomware virus; OS is Windows XP. I tried to remove it with Hitman Pro on a USB drive. I was able to get the USB to boot and run Hitman Pro, but it did not remove the virus. (And I think that the USB from Hitman is no longer able to boot.)
I was going to try other techniques that involved starting in Safe Mode (various versions--with networking, with command prompt), but when I attempt to start in safe mode, the computer simply comes back to the various options for starting up (Safe Mode, w/ Networking, Command prompt, Last successful, normally). Only the latter two work and they bring up the ransomware.
In the self-help guides, it appears that the options all involve either getting to safe mode or running something from the desktop, neither of which appears to be an option currently.
I look forward to your assistance.
