No problem...
LibreSystem is supposedly an anti-spyware program, but I have a strong feeling it's probably a rogue. It was installed by the owner of the PC (friend of mine).
There's more on it here :

French again, sorry... In a nutshell, it says that libresystem.com is one of many domains that are associated with an IP address that is targeted by a malware designed to lure unsuspecting users into buying rogue anti-spywares. Apparently, this was designed last year by a group called SSHijacker.
Before I came to TSF for help, I started by uninstalling LibreSystem (or I thought I did...), among other actions. From what you see, is it still active ?
