Installed 1.5.1.15 now IE won't launch

[Tom.K]

I'm using Google Toolbar 4.0.1601.4978, still using Spybot-S&D 1.5.1.15 (SDHelper enabled) and I don't have any problems with IE.
Maybe there is a problem in immunization.

Nope, I tried de-immunizing without any effect.
The problem definitely is gone with SDHelper disabled and there with SDHelper enabled.

I had a very similer problem with IE 6.02 Where IE would wouldn't load every few tries with the SD Helper on, but when I upgraded to the latest version of IE 7.0 the problem went away

Definitely Google Toolbar related. Uninstalled the toolbar last night and the problem seems to have immediately disappeared!
