What happened? Did you clean the system? Here is a suggestion I have if you are hit by this ransomware. It really works, because I had to do it on a friend`s PC. So here is what you have to do :
Step 1 - go into safe mode with command prompt by pressing F* continuously on restart
Step 2 - in the command prompt line type explorer.exe and wait for the Desktop to appear
Step 3 - go to the Start menu and type rstrui in the search box to go to System Restore
Step 4 - set your system to a previous date when it was clean
Step 5 - when you have unlocked your PC, clean it from FBI moneypak , because it is still on your computer
How to clean the machine from the infected files?
You can do that manually:
1. Check your registry for modifications and new entries made by FBI Moneypak
2. Delete these malicious files:
For Vista:
C:\Program Data\csrss.exe
C:\Users\{Your User Name}\AppData\Roaming\Microsoft\Windows\… Menu\Programs\Startup\ctfmon.exe
C:\Users\{User Profile}\AppData\Local\Microsoft\Windows… [Random.exe]
C:\Users\{User Profile}\AppData\Local\Microsoft\Windows… [Random]
C:\Program Data\lsass.exe
C:\Program Data\[Random.exe]
For XP:
C:\Documents and Settings\{Your User Name}\Start Menu\Programs\Startup\ctfmon.exe
C:\Windows\[Random.exe](eg. Pmfjyiaj.exe)
C:\Documents and Settings\ {User Profile} \Local Settings\Application Data\Microsoft\Windows\[Random.exe]
C:\Documents and Settings\ {User Profile} \Local Settings\Application Data\Microsoft\Windows\[Random]
You can also do all of this automatically with a security tool like
