Much has changed at Celtic Park since their shock semi-final defeat by County at Hampden two years ago, during Neil Lennon's first few weeks as manager, then on a temporary basis.
Lennon has strengthened the Celtic squad and instilled a winning mentality, while his side beat County at Dingwall in the League Cup in September last year.
But Derek Adams' side have also improved - they have not tasted defeat in the league for 12 months - and enter Saturday's next meeting as SPL rivals of Celtic.
Vigurs said: "2010 will always be a great memory but this is the league, this is a completely different Celtic team and Ross County team, so I don't think it will have any bearing on what happens on Saturday.
"People forget things very quickly. As players you can't dwell on games you have won or played well in, or even games you have played badly, because you need to concentrate on the game ahead of you."
Celtic are expected to win the league by some distance this season but 24-year-old Vigurs does not believe they will be streets ahead on any given Saturday.
"Even to pick up a point would be a great bonus for us and a great lift," the former Inverness player said.
"Celtic are a massive side, they have got a big budget compared to everyone else, but I don't think teams are too far away.
"A lot of the sides in the SPL are very good passing sides, just like Celtic, and on their day they can trouble a big team like Celtic.
"It's no different for us. If we are on our day and if they have a bit of an off day there is no reason why we can't have a good game and pick up points.
"If we do the rest of the teams will sit up and take notice."
County have already signalled they will be tough opponents by holding Motherwell and Aberdeen to goalless draws.
Vigurs said: "It has been quite a tough start but we haven't conceded a goal, which is brilliant against Motherwell and Aberdeen.
"But we haven't scored either. It's not so much of a problem right now but we need to start scoring at some stage.
"But I think once the boys settle down that will come and no greater time to score your first goal in the league than against Celtic at home."
