One line's still there, and one I missed earlier.

Make sure Hijackthis is the only thing running before hitting "fix checked".
Run Hijackthis and select "Do a system scan only", place a check by the following entries.
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://ie.redirect.hp.com/svs/rdr?TY... on&pf=laptop
O9 - Extra button: WeatherBug - {AF6CABAB-61F9-4f12-A198-B7D41EF1CB52} - C:\Program Files\AWS\WeatherBug\Weather.exe (file missing) (HKCU)
Close all open windows and browsers, and hit "Fix Checked".
