Trojan:Win32/Tobfy.A is a Trojan that is used to distribute a Police Central e-crime Unit (PCEU) Ransomware to vulnerable computers. Trojan:Win32/Tobfy.A blocks affected PC users from accessing the desktop by displaying a certain image/pop-up alert. The image includes falsified instructions and tricky information about a ransom that you are demanded to pay via Ukash, Paysafecard, Green Dot MoneyPak or Ultimate Game Card to restore access to the computer. The pop-up notification uses the name of the legitimate authority in an attempt to persuade PC users to pay the ransom.

Once installed, Trojan:Win32/Tobfy.A makes system changes on the infected computer system. Trojan:Win32/Tobfy.A may add a hidden random file name on the corrupted machine. Trojan:Win32/Tobfy.A creates the certain registry entry so that it can run automatically every time you start Windows. Trojan:Win32/Tobfy.A terminates several legitimate process names including msconfig.exe, cmd.exe, taskmgr.exe and regedit.exe if they are currently running on the compromised PC. Trojan:Win32/Tobfy.A also closes windows with the title 'Program Manager'. Trojan:Win32/Tobfy.A disables services, devices, and drivers when the computer is started in 'Safe Mode' and 'Safe Mode with Networking' by renaming the particular registry keys.
