There are several versions of the chat messages, which are “cleverly written” to fool users, Arak wrote on the Skype heartbeat blog. The link appears to contain a JPEG photo file, but if clicked causes the Windows run/save dialog box to appear, which asks whether the user wants to save or run a “.scr” file. The file is malicious software that can then access a user’s PC via Skype’s API (application programming interface). The malicious file has been named W32/Ramex.A.
