OK, thanks.. I was finally able to fix it.
What I did was finding these files:
/Library/Application Support/VSearch
/Library/LaunchAgents/com.vsearch.agent.plist
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
/Library/LaunchDaemons/Jack.plist
/Library/PrivilegedHelperTools/Jack
/System/Library/Frameworks/VSearch.framework
move them to trash, empty trash and restart the mac.
Not all of these files were there, only 3 or 4 but it worked...
What a crazy stuff.. for a couple of days I felt I had a windows PC.. what a nightmare.
