Reference to my home page by another site is in my Google site search

Is this a hijack

[eveolasov]

A Google site:mysite.com query shows as a supplemental result www.myhomepage.com/?source=theirsite

The cache is for this is showing a Feb. 2005 cache of my main page.

The hyperlinked title and description are from my Feb. 2005 webpage but goes to my current home page showing its current PR4.

I've noticed since BD my rankings have plummeted from first page #5 to buried deep on 5th page for my main key words.

Could this be the reason? Some sort of dup filter penalty?

How do I remove this without removing my main page.
I am stumped and crippled in the rankings now.

The webmaster who did this to me can't even remember where it was on his site. It's on some dead page.

May be this may help.
