Firefox and Thunderbird: both excelent proggies that were originally named Phoenix/FireBird and Minotaur (respectivly).

One last advice to the starter of the thread:
- if at the end of the day (by some twisted and evil reason ), you still wish to use IE, get SpywareBlaster , a cool *.exe from the fellows at javacoolsoftware that approaches spyware on a different way.
They don't clean it up, this peace of freeware is intended to prevent the spyware from actually reaching your computer, simply by integrating itself within IE.

All you have to do is download, run the proggie, get the last available package of updates and let it do the job.
