I use shark007 codecs and I've not had the ask toolbar installed, either it's not there or there's an opt out.I used to use shark007's pack, but recently he's started force installing the ask toolbar in the installation, you're not given an option for it. The only way to stop it is to download a registry file from his site and adding it to the registry which apparently stops it.
I've simlply stopped using it.
