*Trump signs into law U.S. government ban on Kaspersky Lab software*

President Donald Trump signed into law on Tuesday legislation that bans the use of Kaspersky Lab within the U.S. government, capping a months-long effort to purge the Moscow-based antivirus firm from federal agencies amid concerns it was vulnerable to Kremlin influence.

The ban, included as part of a broader defense policy spending bill that Trump signed, reinforces a directive issued by the Trump administration in September that civilian agencies remove Kaspersky Lab software within 90 days.

In an attempt to address suspicions, the company said in October it would submit the source code of its software and future updates for inspection by independent parties.

It added that the company was assessing its options and would continue to "protect its customers from cyber threats (while) collaborating globally with the IT security community to fight cybercrime."

On Tuesday, Christopher Krebs, a senior cyber security official at the Department of Homeland Security, told reporters that nearly all government agencies had fully removed Kaspersky products from their networks in compliance with the September order.
