5GG,这是Virus问题,跟你firewall无关。因为你使用免费网络保安软件Avast Web Shield。Avast Web Shield能保护你的电脑避免受到网络攻击,它会扫描您访问的网站,并阻止任何检测到的恶意代码。同学网有部分代码behaves像Viruses一样(你电脑显示是木马病毒),所以Avast Web Shield会自动把同学网block住保护你的电脑避免受到网络攻击,令你不能访问同学网。要绕过Avast和访问封锁的网站,你需要将网站添加Exclusions list,或停止Web Shield,
方法一(建议用)
Adding Websites to the Exclusions List
1) Double-click on the "Avast" icon in the system tray to open the user interface.
2) Click the "Real-Time Shields" tab on the left and then click the "Web Shield" item.
3) Click the "Expert Settings" button to open the Web Shield settings window.
4) Click "Exclusions" at the left.
5) Click once in the "enter address" box in the "URLs to exclude section" and type the URL of the website. (http://www.75one.net/)
6) Click the "Add" button to add the website to the Exclusions list.
7) Add all websites that you want to visit and click "OK" to save the new settings and close the window.
方法二(不建议用"Stop Permanently")
Disabling the Web Shield
1) Right-click the "Avast" icon in the bottom right corner of your screen (in the system tray) and select "Open Avast! user interface" from the context menu.
2) Click "Real-Time Shields" in the navigation pane at the left to view all modules.
3) Click the "Web Shield" module on the left to view its settings in the right pane.
4) Click the "Stop" button to disable the Web Shield.
5) Select "Stop for 10 minutes" to briefly stop the shield or click "Stop Permanently" to permanently stop the module.
6) Click "Yes" to confirm the action and disable the module.
