I recently purchased BitDefender AntiVirus 2009. Installed on my laptop and my HTPC. Network traffic in my home network is since very much slower then before. Moving a file from my laptop to my HTPC works with a maximum of about 1 to 2 MB/S instead of the 6 to 7 MB/s before. Looking at the file activity monitor on both my laptop and my HTPC does not show that much activity. Internet traffic doesn't seem to be affected.
Any ideas?
