No Redirect URL's

Anyone see these showing up in the SERPs?

www.domain.com/page.htm?no_redirect=true

One of my sites is losing indexation of the correct
page and this is replacing it in the search results.

It has affected about half of my pages so far and
I need to find a fix quick.

Any Apache/Directives gurus out there that can
point me in the right direction? Or could this be
a malicious attack of some sort (I am the top
dog in a VERY competitive niche/market)?

I really heard this type of problem very first time. Maybe Google Change their Algorithm or You site is virus infected.

Try this.

In webmaster tools, go to Crawl>URL Paramaters>Add parameter. From there, add the URL variable "no_redirect" in the box and in the drop down box, select "no" and then save.

Thanks anyway but I figured it out. It's an issue with godaddy hosting, nothing malicious - although having godaddy as a host provider feels malicious at times.
