It is working now, i simply restored the file that was on quarantine. Then i went to the game and notice how slow the game was! Really really slow, the ping was normal ... i usually have between 62 to 76 and it was 70 but ... i went to the deskot and made the ctl+alt+del and notice that freelancer.exe was using 50% of the CPU. I exited feelancer, removed freelancer.exe that still was on the list, started the game again and all fine. at the moment is 0%. later i will restart this PC and see if happens again and make a full scan.
Take care all
Edit: Ok i made a restart of my PC, and entered again on Freelancer and again the game is very slow, i checked again and freelancer.exe was agan using 50% of the CPU. I exited freelancer and removed it from the list, entered again on the game and all fine!!!! Anyone with the same problem?
