Nabload.U is a Trojan that downloads a password stealer type Trojan, called Banker.BSX, to the affected computer.
Banker.BSX captures the actions carried out by the user in several websites, including the login and password typed by virtual keyboards and sends the data it has gathered to a certain email address.
Nabload.U is distributed via MSN Messenger. When a computer is affected by Banker.BSX, the latter sends an instant message to all the addresses in the Contact List. The message includes a link that points to a copy of Nabload.U.
With the Nabload.U Remover you'll be able to easily get rid of the virus infection form your computer.
