title: Postgresql 8.4 and BitDefender 11
body: <p>Since I've change my antivirus to BitDefender 11 I cannot start Postgresql 8.4 on my desktop (command line or service alike). Browsing on the Internet is seems that is a known issue, since many people are complaining about this issue
  Does anyone know a workaround to this issue?
  Thanks</p>
