Gmail (using Sophos) detects my Keylogger when I send it as an attachment but that crappy Norton used by Yahoo doesn't detect.....Heard about it and seen it, it's no good.
Get NOD32 or Kaspersky. Use avast Home or Avira AntiVir free but don't ever use that crappy AVG......never heard of it but i use avg free edition
Me too never heard abt Sophos !!
NOD32 works great for me !!
