please be informed that analysis of this situation needs more outputs (AVG logs, configuration) from your computers. Please contact AVG technical support from one affected computer through AVG diagnostic utility - http://www.avg.com/filedir/util/support/runner_en.exe - please enter your email address (you want to receive answer to) and description of the situation, plus:

- if AVG Firewall profile "allow all" will solve it
My problem appears to result from my current configuration of the Firewall provided automatically by AVG Internet Security (vrs downloaded: avg_ipw_x86_all_2011_1136a3181) and unfortunately I?ve not yet got my head around the firewall blocking features of this software.
I have 4 machines connected to a D-link 635 Wi-Fi router.
2 machines are desktops running windows 7 and include AVG Internet Security, both machines are set-up as Small Home or Office Network and are on a homegroup, so can share files and printers. The 2 other machines are laptops running windows XP.
One of the laptops is on AVG Internet Security which has been automatically set-up as a Small Home or Office Network, whereas the second laptop is running Zone Alarm Firewall (Free vrs) and AVG Anti-virus (Free vrs).
I recently set-up the router configuration rules to allow me to plug in a USB external hard-drive into the USB connector on the D-Link router to create a ?Network Drive and I also installed the latest vrs of D-Link?s SharePort utility on to the 2 laptops. The SharePort program automatically runs at start-up and will allow a machine to see and then allow the user to manually connect/disconnnect to/from the new ?network? drive, although it only allows one machine to connect at a time.
? First on the laptop running Zone Alarm Free and AVG Anti-virus Free, the Zone Alarm firewall asked me to ?allow? SharePort, which I confirmed. The network drive then appeared with a drive letter assigned and I?ve been able to automatically see/connect/disconnect to the drive (read/write access).
? With the laptop running AVG Internet Security, initially when I installed SharePort it automatically executed and displayed a box indicating that the firewall must be reconfigured to allow TCP out port 80:20005 and UDP outport: 9303.
? After clicking OK to the SharePort message, the firewall then asked for me to confirm what setting to apply to SharePort, which I chose ?allow all (recommended)? and checked the save for future box.
? The firewall than confirmed Small Home or Office Network was operating.
? I then clicked on the SharePort icon in the tray and it displayed a box indicating the USB drive is not accessible.
? I then checked the Firewall Traffic log, which displayed numerous entries for every 10 seconds:
o Application = SYSTEM
o Log Action = Blocked
o PID = 4
o Direction = Out
o Protocol = TCP
o Remote Port = 20005
o Local Port = starting at 1400 and then incremented by 1 or 2 for each entry
o Remote IP = nnn.168.0.1
o Local Port = 0.0.0.0.
? Next I ran the Firewall wizard and change the setting from Small Home or Office Network to Allow All, which effectively disabled every blocking setting.
? Shareport icon in the tray changed from Red to Green and on clicking allowed me to connect and disconnect to the Network Drive.
? I have subsequently changed the firewall back to Small Home or Office Network and the wizard indicated that it had applied Network 1 settings automatically.
My goal is to have all 4 machines accessing the Network Drive for file sharing and back-up, so would really appreciate a step by step guide as to how I manually change the firewall settings to insure top notch security whilst getting AVG Internet Security firewall to allow access to the Network Drive.
