Boot.tidser.b

Boot.tidser.b is a detection for a variant of Tidserv Trojan that is able to infect 64-bit Windows operating systems. Boot.tidser.b targets the Master Boot Record (MBR) of the affected computer system. MBR will be replaced with a malicious version that may result in PC system crashes. The infected MBR hooks BIOS functions which in turn patch the Windows kernel as it is launched. The patched kernel then starts a malicious driver from Tidserv's encrypted file system, which is set at the end of the disk. The threat thereby bypasses protection mechanisms existing on the PC system and is thus able to install itself as a rootkit. Boot.tidser.b is a serious threat which needs to be removed from the infected computer as quickly as possible.
