New blended worm in the wild !
ESET: Win32/Zimuse.A is a type of threat that overwrites MBR (Master Boot Record) of all available drives with its own data, making the data stored on the user’s computer inaccessible. Moreover, the restoration of the corrupted data is complicated, requiring specialized software or a provider. [...] Presently, the greatest number of infected computers is in the United States, followed by Slovakia, Thailand and Spain, followed with Italy, Czech Republic and other European countries. [...] The worm uses two ways to spread – either via embedding in legitimate websites, in the form of a self-unpacking ZIP file or as an IQ test program, or via Exchangeable media, such as USB devices.
BitDefender: ... this malicious piece is extremely dangerous; unlike average worms, it would lead to severe data loss as it overwrites the first 50 KB of the Master Boot Record, a key zone of the hard disk drive.
