Trading was suspended for an hour at Russia’s main stock exchange because of a computer virus, the Russian Trading Systems, or RTS, said Friday.
Data processing was paralyzed late Thursday afternoon as specialists rushed to localize the virus and switch off the infected computer, according to a statement from the exchange. No permanent damage was caused and no information was lost.
Spokeswoman Zoya Konovkova said it was not clear what virus had led to the shutdown.
According to RTS vice president Dmitry Shatskoi, the virus entered the system via a computer used to test new software, which was connected to the Internet.
