What is the name of the virus, which is unofficially responsible for the delay in IRAN's nnuclear program?

Stuxnet was a sophisticated computer worm discovered in 2010 that specifically targeted Iran's nuclear enrichment facilities at Natanz, causing centrifuges to spin out of control and fail. This cyberweapon, widely believed to be a US-Israeli joint operation, significantly delayed Iran's nuclear program by destroying nearly 1,000 centrifuges. The other options (nuira, globalnet, Fox) are not real malware names associated with this incident.
