Microsoft has warned that a new Trojan horse actively spreading in wild, particularly on computers running Windows XP. Trojan:Win32/Daonol malware steal credential information, redirect web traffic, and also protects itself by keeping some security-related software from running. “Several recent versions of this malware are buggy and prevent computers from successfully shutting down or (more importantly) starting up. If you have (or someone you know has) a Windows XP system which won’t boot completely (ie, shows the ‘Windows XP’ splash-screen with the progress bar, but then the screen turns black and the system never starts up completely), it’s likely a Daonol infection. Another obvious symptom of infection is that regedit.exe and cmd.exe will not launch properly,” MMPC.
