in the past few weeks, there have been strange adds playing on my computer at random times. Usually I don't have a browser running, or much at all running for that matter. However, commercials (audio) just start playing on my speakers. It just plays one, then more at other random times. I've looked for information on this, but I haven't found anything. I'm wondering if this is a virus or spyware or anything of the sort, and even more wondering how to get rid of it!
Oh yes and if it helps at all, commercials usually range for new movies out in theaters, 'Dora the Explorer' advertiesments
and a few others mainly- however there isn't much variety.....
Thanks to anyone who coudl help at all
