Daprosy worm was a malicious computer program that spreads via local area network (LAN) connections, spammed e-mails and USB mass storage devices. Infection comes from a single read1st.exe file where several dozen clones are created at once bearing the names of compromised folders. The most obvious symptom of Daprosy infection is the presence of Classified.exe or Do not open - secrets!.exe files from infected folders.
