Thank you John
it's more clear, ( but was not easy to see if SU change only SU keys)
I have not observed any troubling , just the informatons in the log of my FW
I think that the post is close now

Thank you for these precisions
Yes you are right ...i am a little bit paranoid
I know that my ISP log all of my Internet-traffic or emails but these informations are not used for commercial approach
But always ...no response about the reason for which SU change keys in the registry

Thank you all for your numerous responses.

I have stated that:

-SU tries to connect then it does not work because I no longer use it for 1 year,

• I disabled the automatic update but it continues.
• I still do not understand why, when SU is not used, it changes the keys to registry
• Mac1's remark makes me fear much
• As Mitcorb I think developers should answer
• I have blocked access in the firewall
• But I have no more confidence in SU especially as Google is known to use user information
• In conclusion I uninstall SU

Thank you for your opinion
