Hello, I have a Sony Vaio laptop with windows 7. I do not have internet access at home and rely on friends,libraries etc to do this. A few weeks ago the laptop was infected with the "police trojan" . I used trojan killer to remove it and then malawarebytes and combofix to rid the laptop of the remains.However, since then i've been unable to get online and although everything else is apparently ok i have no wifi. Please Help,thanks
