Thanks Birdy for going to all that trouble. I wasn't linked to Limewire from another site. I accessed the site and then clicked on the links that took me to the page to download.

By other files do you mean, did I download a song, and then the ads started popping up?

The ads appeared to start popping up "very shortly" after I downloaded Limewire. At this point I can't recall if I had downloaded a song immediately or not. I don't think so, because I had never used it before and I didn't have a clue what to do until I had a chance to study the pages on the site. The ads started appearing almost immediately.

I have just removed Limewire from my computer using add/remove but I also went through and removed the file in Programs, and from my task bar, and from my start up list. A friend suggested that I google a CiD and Zedo tool kit to remove them from my system, as he said they can imbed themselves deep into my computer.

I will install the adware you suggested and the removal kits and clean my computer again, and then download from the link you provided. That is odd that I managed to find an accelerator if I was using the official site.

Thanks so much for all the effort you have gone to on my behalf, it is much appreciated.
