Hi
Am rather perplexed about the network traffic that is being received and sent out.
The system is a XP SP2. PC is connected via a cable to a TPL router with wireless HW modem attached.
Has firewall ZA which used to work fine until a deluge of attacks (over 500 within a few seconds trying to access the PC). Could be the settings of ZA not well done then. But the originally set MS firewall became inoperable due to ICS being unable to activate, even though tried directly.

Have scanned with many AV such as SD, MalwareB, AVGfree, MV, etc - all negative but the traffic is still like being redirected immediately as TCPView shows.

In the past, the traffic when the HW modem was directly plugged into the PC usb port, the traffic sent out through the local area connection is usually about 10% of that received. However, it has since gotten to be about equal ie packets sent almost equal received. This happened since sometime ago with or without the router though the addition of the router could have been a cause. Why, because initially it couldn't log into the internet if the port is not allowed to open as a server.
So there is a this question why Generic Host Process for Win32 need to be server in order for the PC to access internet?
Logging in is by firstly enabling the LAN, then plugging in the modem attached to the router.

The HWei modem recently has a liveupdate program running (it didn't use to have). My PC accesses the internet through the national proxy server. Disabling the modem liveupdate didn't seem to affect the access once logged in. The TCPView log attached has it disabled.

On the Windows Task Manager, System Idle Process is high at 70 level; and taskmgr.exe is active in top 3 postion besides the browser in 2nd position.
alg.exe appeared as a server on internet log in
AVGfree is running but it shows 2 avgsrvx.exe

It appears, according to the Local Area Connection Status, that the amount of traffic is immediately transferred from the receipt to the sent. Does this mean it is being redirected?
It appears so as a check found some being redirected to various sites - google, some reseved sites, research sites, etc. Can anyone help to confirm, and if so, what can be done to stop the outflow? Thanks.

Following is what appeared on the TCPView file. Noted that TCPView deletes records as the page changes so have tried to get the page upon loading.

Hello,I think we should get a deeper look. Please follow this Preparation Guide and post in a new topic.

Let me know if all went well.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook
