It spreads through executable file infection (through infected USB sticks and other media), and more recently, through compromised HTML files (thus infecting vulnerable browsers visiting compromised websites). It has infected computers associated with at least 890,000 IP addresses in Poland. In 2012, Symantec estimated that the botnet had control of over 300,000 computers worldwide, primarily in Egypt, Pakistan and Southeast Asia (including India). A Kaspersky report listed Virut as the fifth-most widespread threat in the third quarter of 2012, responsible for 5.5% of computer infections.
