A fellow list member commented on the number of popups he got while visiting
my vanagon website http://neksiwel.20m.com/ . A shame  but to be expected.
Here are a list of free downloads I have been using for some time. I get no
popups anywhere I go.
 http://tinyurl.com/5kgsl   Adaware, to clean ad ware.

http://www.safer-networking.org/en/mirrors/  SPYBOT, this is a great
program. Use the advanced version.

 http://tinyurl.com/3vcux  SPYBLASTER, helps stop popups.

http://www.tucows.com/preview/355220.html  REGCLEANER, while you're at it,
clean your registry.

And of course I have Nortons.
