I have had to dump McAfee V Scan and Firewall and apparently Zone alarm is also cited in creating synchronisation problems. I have moved to NOD32 for Virus protection and have temporarily enabled XP's firewall (what is wrong with this?). I am looking for another firewall (unles XP's is ok- it puts my PC in stealth). I am interested in a free one such as Kierio or Sygate but am concerned they may also mess up synchronisation. Does anyone have any views / experiences with this? Thanks. R.
