... Adware/Malware. I believe it is coming from some of the Google extensions and also from Vaudix movie player and/or DivX movie player. I had all of my Google extensions removed and both movie players removed, then I regedited old stuff in my vista by right click delete and delete all lines and keys that relate to that deletion, (be sure not to delete the custom category in regedit. I just started deleting lines and keys from the last line to the custom category, if that makes sense. I didn't have a problem again until I had to uninstall and re-download both Vaudix and DivX. Now, I may have to go through the same process again. Also, check the options tab in your Google extensions to see if you have anything else checked that you are not sure of. Hope this helps some of you. I have not had to re-install my Vista disc. The world could be a better place
