I downloaded Ad-aware on my desktop and on my laptop a while back and now I can't get it to update on either computer. Everytime I launch the program it comes up with an error message when it tries to connect to update the spyware definitions. Anyone else have this problem lately?

I did try to download the Avast anti-virus software after Erik recommended it, but because I already had an old version of Norton AV it won't work unless I remove Norton, which I'm not eager to do.
