Malone scored 14 points as the Exiles comprehensively defeated Brive
London Irish are back on track in their Heineken Cup group after a thumping bonus-point win over Brive, who had Guillaume Ribes sent-off.
The Exiles, who lost to the Scarlets last time out, went 15-3 ahead with tries from Chris Malone and Tom Homer.
Their dominance continued after the break, Steffon Armitage, Richard Thorpe and Homer completing the scoring.
The match threatened to boil over in the second half and Ribes was dismissed on 67 minutes for dangerous play.
Malone was instrumental in Irish's victory with a 14-point tally.
He set the Exiles on their way to a deserved success with the pick of the tries by beating three defenders before dummying Brive full-back Horacio Agulla to touch down under the posts.
Centre Seilala Mapusua was a constant threat in midfield and slick hands found Nick Kennedy waiting in space.
The England lock then passed to Homer who crept home in the left corner.
On the stroke of half-time Brive finally got on the scoreboard as Palisson hammered a long-range penalty to give them some hope.
But the visitors kept up the pressure after the break with three well-worked tries.
Armitage benefited from weak tackling from replacement Jean Baptiste Pejoine to score following neat work from Malone, Seveali'i and Homer.
Tempers flared in the final quarter as Brive's Ribes was sent off for a punch on Danie Coetzee before the South African hooker and Jean-Philippe Bonrepaux were sin-binned for fighting.
After the home side had been reduced to 14 men, the Exiles earned the bonus point with 12 minutes remaining thanks to the out-stretched arm of Thorpe who had galloped onto Malone's pass.
Homer had the final say with his second try in the right corner in the final minute, leaving Lamb to complete the scoring with the conversion.
London Exiles coach Toby Booth:
"We are delighted with the result because it was important to keep our hopes alive in the pool. It's a massive boost for us.
"We knew that Brive had beaten Toulouse last weekend and would come into the game in confident mood.
"It was important we took care of the win first and the added bonus was the extra point."
