i already reduce the sensitivity of the web shield into (low)
but i do not try disable.
i understand that this new release is design for 64-bit system.
maybe for some users that using high speed net connection the reduce in speed is unnoticeable.
i did unchecked the "enable web scanning" and the speed back to normal.
edit: i mean i did not try stopping web shield i think "unchecked enable web scanning is the same as disabling " i am confused in using terms
You have effectively stopped the web shield if you don't have the "enable web scanning" option checked.
I don't know where you got the idea that this new release is designed for 64bit (not that that would make any difference to downloads/speedtest, etc.). Best not to speculate.
The only additional thing for 64bit is the boot-time scan. There have been elements for 64bit OSes for some time but it isn't a native 64bit version. It is a 32bit program version which can adapt itself for 64bit OSes when installed on a 64bit OS.
I doubt lowering the Sensitivity would make much difference as the traffic is still going to be routed through the proxy I have mine set on Normal (the default) I used to have it on high, just that I forgot to bump it up after a clean install after the beta trial.
Those on high speed broadband are possibly more likely to see a difference as they are going to be pumping more data into the proxy to be scanned.
I just ran a test on that XP SP3 link on page one with the web shield running and was getting up to 5MB/s download speed, when I did the snapshot it was reporting an average of 4.3MB/s which is the fastest I have ever had (after my TCP Optimize spell).
