Microsoft security just keeps getting worse
It has just been announced that a new Trojan Rootkit can embed itself so deep into the Windows operating system, that a complete format of all data and a fresh re-install is needed to get rid of it, as it hooks itself to to the hard disk port driver for protection and then hides in the machine’s boot sector.
From Microsoft Malware Protection:
The bootkit malware Trojan:Win32/Popureb.E has made some changes in its code compared to previous samples (specifically, Trojan:Win32/Popureb.B), and now it introduces a driver component to prevent the malicious MBR and other malicious data stored as disk sectors from being changed. The driver component protects the data in an unusual way – by hooking the DriverStartIo routine in a hard disk port driver (for example, atapi.sys).
Does your Windows computer feel sluggish today? You may just have the unremovable Popureb.E Trojan Rootkit offering up all your private data to the world!
