OT: PC Virus?

[John Penney]

Good Morning gentle listers of the PH and HP world- Please forgive the bandwidth but I am one frustrated puppy:

Somehow or other I have the following phenomenon on my PC at home and would like to know how to eradicate same- whenever I open a text message in Yahoo mail, the screen appears to invoke a program which creates links via underlines on selected text, e.g. the , house, hello-  to a Web page which purports to offer everything from cars to homes to ... you get the picture. I tried a couple of the non-cost variety virus scrubbers but still have this strange thing happening. Help!

Thanks to all and Happy Thanksgiving! Wake at 5:30 at The Spar, Olympia, WA
