The Stuxnet computer virus has a twin, Reuters reports. It is called "duqu" because it creates files with the letters "DQ" in the prefix.

Cybersecurity experts say the malicious code can collect data, then lie in wait for future attacks.

Computer company Symantec says the virus is very similar to Stuxnet and coul essentially act as a precursor to a future Stuxnet attack.

The Homeland Security Department said it's acting on the reports.
