popups leading to off BYC locations like surveys for Walmart cards???

In the messages (public and private) section.   There will be pop up linking to different places off BYC if you click it.  You'll see an underline under the word and the word will be bolded.  It appears to pick on certain words.  It appears that the words Thank  trigger it. There may be others.

I have a public message from Kansasque so I hope it's okay to post it here so you will see the problem

My eggs arrived 2 days after being shipped, all very carefully wrapped and packaged, and with a nice note enclosed. Only 1 fell victim to the trip, and, since she was generous with the extras, I've still got 15 going into the incubator. Hatch day is April 26th and I can't wait : ) Thank you, Nancy!

If you click the Thank you above, it will take you out of BYC and this is where you go.

when you clicked it goes to answer it has in a block Answer this one question and win a walmart card

click there and it asks you to takes you to the survey

Then after in that it takes you to the survey.   I'm going to run a full virus check but wanted you to know about this.  I'm in Mozilla Foxfire and operating windows 7  ...Appreciate it   & have a blessed day.  Nancy

Eureka, I think I've eliminated the problem.   Although it did NOT  show up in any of the virus checks or even spyware that I have, I researched quite a few dialogues about similar problems and finally eliminated a program on the operating system that somehow self installed itself! .   Popups have disappeared Knock on wood....  I'll be sharing with Nifty-Chicken the specific site I used that helped us.  

And thanks so Nifty, for responding so quickly!

VFEM, I did a virus check and also a checked block popups. After a great deal of research, I took the advice of  http://wafflesatnoon.com/2011/10/05/seeing-unwanted-text-enhance-ads/   and eliminated Facetheme which had self installed itself on my computer. And I still don't know how or when...  It's a key word grabber. it was highlighting and underlining key words - which triggered popups to all kinds of places.  I'm not an authorized computer repair person, but it seemed to work for me.  Hope this helps you!
