Backlinks to irrelevant page

Hi everyone, we`ve got a little business website. It was not ranked very well, but it was ok. On our website we have a page, where we sell some Jquery plugin developed by us. This page is not listed in menues, its a separate page, located on our main domain. www.mysite.com/plugin.html. Several monthes ago our main site disapeared from google search on all relevant keywords (pages still can be found with site:www.mysite.com). Now i`ve realised, what can cause the problem. We`ve got about 500 backlinks to our main domain. But there is an url of plugin page in a comment in a JS code of plugin. Someone has installed our plugin on a big online shop and ve`ve got about 35000 backlinks to the plugin page! I think, now google thinks, everyting else is irrelevant on our page. Can it really be a problem? And what can we do the best?

I`ve tried to remove plugin backlinks wit disavow, but in about 2 weeks only several hundreds from 35000 backlinks disapeared. It can take years for all backlinks to disapear with such a speed.

So, once again, questions:
1) Can so many backlinks to irrelevant page make google think, this page is the main one? Or maybe google have applied some kind of ban?
2) What can be done?

Thanks
