Iranian media reports say the country's nuclear agency is trying to combat a complex computer worm that has affected industrial sites in Iran and is capable of taking over power plants. 

The semi-official ISNA news agency says Iranian nuclear experts met this week to discuss how to remove the malicious computer code, dubbed Stuxnet, which can take over systems that control the inner workings of industrial plants.

Experts in Germany discovered the worm in July. It has since shown up in attacks in Iran, Indonesia, India and the US.

Friday's report said the malware had spread throughout Iran, but did not elaborate. Foreign media reports have speculated the worm was aimed at disrupting Iran's first nuclear power plant, which is to go online in October.
