Russian security software company Kaspersky Lab has been having a bad few months amid allegations its signature anti-virus software scans for and identifies files of interest to Russian cyber spies. Kaspersky publicly contends a high-profile incident in which it allegedly stole classified files from a National Security Agency contractor's computer was due to dumb mistakes on that individual's part, but that hasn't stopped the US government from banning the use of the company's products at federal agencies.
