installed norton antivirus latest, said it removed
1 day later, norton got removed, empty norton folder
put in avg, said trojan horse generic30.wav found, removed.
came back again.
1. do i need to turn off system restore; afraid that if it crashes, i don't have any restore point to boot up the computer.
2. does anyone know how to remove the trojan. I bought norton antivirus 2013.
