Does NOD32 affect network speed?

Hi,
NOD32 scans everything before they're opened. Right?
What I realise on the trial is that NOD32 downloads pictures and scans them before displayed on my internet browser. Without NOD32, pictures were shown as they were downloaded.
I know NOD32 doesn't slowdown my computer but can it affect my internet speed?

 

Not to any noticeable degree.

Cheers

 

Nod32 has no noticeable effect on network speed that i can percieve. Your choice of firewall however will effect its speed.

 

Which quality firewalls are low on resources and have no affect on internet speed?
I know Look 'n' Stop says my connection can run at peak performance while using its firewall but you have to pay for that. I heard there are many good ones where you don't have to pay.
Thx.

*I did a leak test on NIS 2007 and it got penetrated on the first go. This was because it auto set the setting to 'custom' for this leak test. Default settings for NIS 2007 allows its firewall to auto set rules for programs without user interaction. This can be good but also bad. I opened up NIS2007 to block this leak test program and it got blocked when I tried the test again.

 

high performance firewalls: Jetico, Ghostwall, OA firewall, Sygate, Kerio 2.1.5. Not sure about Comodo, Kerio 4, Outpost and ZA.

 

Packet filters (such as CHX-I) would be the lightest afaik.

free firewalls you can try: Kerio 2.x (though discontinued) or Comodo

 

Since the Nod question has been answered....I have moved this thread here to our firewall forum for the non Nod32 firewall related discussion.

@huangzhengliang,

I have not seen any direct affect from NOD on my internet connection speed. I have seen some slight slowdown when I install a firewall that makes changes to the LSP(Layer Service Provider ~ info) possibly as there may be some slight conflict with NOD IMON (IMON is NOD Internet Monitor) which does have settings within the windows LSP.

 

Filseclab and CHX have least impact on network speed IMHO.
