My Home page is Google. I am not at my PC now so I will post a screen shot when I get home tonight. When I open Firefox, the page opens with the familiar Google Logo and the Search box, but under the Search box I get an applet appear about the size of a banner with an animation of sorts - different each time I open FF. In very light text just under that applet, are the words "This Ad is not part of Site"
I say "Spyware?" with a question mark because I always understood spyware was not a factor on a Linux system and I was surprised. Something got into the FF Browser somehow - executable, Java vulnerability, - whatever.
This is a new system just installed about a month ago !
I'll follow suggestions here about the FF profile etc but first I want to try to understand how and why this is happened.
