US intelligence source make stuff up ..
"Russian government spies extracted NSA exploits from a US government contractor's home PC using Kaspersky Lab software, anonymous sources have claimed."
In other words, we're just making this shit up. Lets just call it what it is, certain US commercial interests want to deny market share to Kaspersky under the pretext of national security.
"The clumsy snoop broke regulations by taking the classified code, documentation and other materials home to work on using his personal computer, which was running Kaspersky's antivirus"
Listen, no self respecting hacker would keep 'classified code' on a computer connected to the Internet that requires anti-virus software. and no self respecting spook would be caught using Microsoft Windows to do their spying.
