Ivan Sproule scored the only goal of the game against his former club as County made it 10 points out of a possible 12 from their last four outings.
Adams said: "It's another good win for us - it's good to keep the momentum going. We are six points off Hibs with two games in hand and four points behind Aberdeen, so we are doing well."
Adams was especially delighted with the performance of match-winner Sproule, who went off injured before the end.
He said: "It's been an excellent start to the year with 28 points now and Ivan Sproule has played a big part in that with three goals and an assist in the three games he has played.
"He has a problem with his hamstring but we're not ruling him out of Saturday yet as it doesn't look like it's a tear."
Hibernian manager Pat Fenlon lamented his side's lack of creativity.
He said: "We did all right in the first half, there was nothing in the game. We had enough of the ball but we didn't create enough chances.
"You're concerned when you are not scoring goals - we gave one chance away and we lost the game.
"There was very little in it. We didn't have that sharpness or cutting edge tonight when we needed to create more chances. We had a lot of forward players on the pitch, we should have been able to do it."
