Ursnif is a data-stealing Trojan that records what a victim types on a computer, what sites they browse to, what is copied into the Windows clipboard, and what programs they run. This information can then be used to either blackmail a victim, steal money, or perform identity theft. The Trojan is commonly spread through SPAM email attachments that download and install the Trojan on a victims computer. To remove the Trojan, and possibly other Trojans, you can use the removal guide below.
