Hello, Saw this in a newsgroup and checked it out. You can get a free copy of IClean ( what was Internet Sweeper) after you fill out a survey. I downloaded it, but didn't install it yet. Here is the URL http://a388.g.akamai.net/7/388/1603/0001/www.freebizmag.com/emailiclean01Welcome.html This is what it said on the download page WINDOWS PRE-REGISTERED COPY IMPORTANT! This particular installer is pre-registered. You will not need a serial number to install and run this application.
