* no actual infections were present on the computer where these images were taken from

Technical Description:
When first run it only creates a copy of itself and registers it at start-up, after which it deletes itself (by using the batch self-delete technique).This newly created file is named by using a sequence of digits followed by an .exe file extension (like 17522964.exe) and is located in a sub-folder of %appdata% named in the same manner (for example C:\Documents and Settins\All Users\Application Data\17522964).
Being registered under SOFTWARE\Microsoft\Windows\CurrentVersion\Run, this copy will be executed at every system start-up, mimicing a full system scan and displaying scary (and also fake) results - like the ones from the pictures above, trying to make you pay for the product activation.
