[anthemextent]

its not that im a bad person but someone was selling a stolen sony vaio vgn-ar11b and i took it cause it was a big chance for 370 euros thats why i took it only because i dont have enough money to buy it from the stores but now im afraid that there may be a problem if i try to surf on the internet cause its stolen and i dont know what could happen mayby they block, lock my laptop or something like that im going to format it but i dont know if that its enough to be safe on the internet pls answer me.. and by the way the laptop i think was stolen by stores when anarchist was burning everything in Athens here in Greece thats why i took the chance and i buy it if it was stolen by a person then i never was buying it. its not an excuse or that im acting like good person but anyway pls answer me. Thanks
