Maloney rifled home a free-kick deep into injury time after toiling against 10 men for 70 minutes to secure a point that was insufficient to lift them out of the bottom three
It was his fifth goal of the season and the 30-year-old Scot was pleased to have delivered after producing what he considered to be a sub-standard display at Loftus Road.
"It was needed because it was one of my poorer performances for the club, so I needed to do something to try and rescue the match. Fortunately the free-kick went in," he said.
Maloney was hardly alone in his frustration as most of Wigan's players struggled alarmingly as they failed to take advantage of Bobby Zamora's 21st-minute dismissal for kicking Jordi Gomez in the head.
"After the game we realised that for 85 minutes or so it was a disappointing performance from us. Our manager told us that at half-time," Maloney said.
"It wasn't quite good enough from us for large parts of the game. It wasn't because of nerves.
"When they went down to 10 men they shifted into two banks of four with the loan threat up front. It probably had the opposite effect on us, we took our foot off the gas.
"We didn't want to, it's just something that spread throughout the team, particularly the forward players, myself included. The passing and movement off the ball just wasn't good enough."
