The bridge.dll problem is a new one and didn't come with either one of those programs which have been on my computer for a year.
Your log looks pretty clean, overall. You have thebridge.dll entry, but no associated BHO (browser helper object) entry. This is good!
You do have GMT, which is Gator/Claria adware and should be removed--see if it's listed in the Add/Remove Programs menu first. The utility for that purpose that I keep coming back to is Atomic Clock Sync .
Weatherbug is adware, but I tolerate it because it's useful. You be the judge.
Here's what to remove:
O4 - HKLM\..\Run: [RunDLL] rundll32.exe "C:\WINNT\Downloaded Program Files\bridge.dll",Load
O4 - Global Startup: GStartup.lnk = C:\Program Files\Common Files\GMT\GMT.exe
Then reboot, follow the paths, and remove:
C:\WINNT\Downloaded Program Files\bridge.dll (file only, but probably missing)
C:\Program Files\Common Files\GMT (whole directory)
