Firewall 11 cripples SMB connections ?

After two days of trying to find the root cause of a degraded write speed to both my NAS servers, I think I found

the source of the problem. It's the new VirusScan Plus 2010 edition I installed.

Before with the old version: 30-50 MB/s

With the new version 100-200 KB/s

I tried to open the usual ports (445, 137-139 etc) but no effect on the speed whatsoever.

Only after deinstalling McAfee things are back to normall again.

Have more people seen this ?

Before someone asks me to run chkdsk (no offense) I'm running Windows 7 x64 on a PC with a Gigabit ethernet i/f.
