Kaspersky defends antivirus firm
"All this bad news about us - it's not true," Eugene Kaspersky tells the BBC.
The Russian antivirus provider Kaspersky sells its products worldwide - but now the Trump administration has ordered US government agencies to stop using the company's products. The BBC's Rory Cellan-Jones speaks to Eugene Kaspersky.

During the recent hurricane and flooding in Texas, an app called Zello which turns a phone into a sort of walkie-talkie was widely used by people trying to get help. We speak to Holly Hartman, a teacher at Memorial High School in Houston, who used the Zello app to help co-ordinate rescue efforts.
And following the Equifax hack, British entrepreneur Nick Halstead says we need to decentralise data.
Rory is joined by BBC Technology reporter Zoe Kleinman.
