Jetclean and bluesprig toolbar

Hello.

I noticed LaserWraith posted ‘Probably the Best Free Security List in the World’.
Jetclean is included in this list.

The point with Jetclean is that it offers to install the ‘bluesprig toolbar’. I stopped the Jetclean installation when I was asked to install this toolbar. There was no information on the bluesprig website. A quick search with Google describes it as an adware and a browser hijacker:

What took me by surprise is that the developer of a junk cleaner would insert adware in its program, although the user is given the choice to install it or not, and that the junk cleaner developer is also developer of adware. BlueSprig defines itself as “your one-stop shop for security, privacy, performance and efficiency solutions for mobile devices and PCs”.

I scanned the installer with Comodo Internet Security and did not detect any threat.
I found a useful discussion at:

Do you know something about Jetclean? Did someone of you install it and find some threat after the installation? Would you recommend it anyway without toolbar?

Many thanks in advance.
