Q: My ISP wants me to use their HTTP proxy server for accessing the Internet.
In the Internet Explorer options dialog I can see my proxy server address is set as proxy.myisp.net, and the port as 3128 (or any other address/port details).
How can I configure the 'Web Shield' to work in this situation?

A:

On NT-based system (Windows NT, 2000, XP, 2003):

1. Right click the avast (a) icon in the taskbar.
2. Choose "On-Access Protection Control"
3. Find Web Shield in the provider list and click Customize.
4. In the line "Redirected HTTP ports" add the port of your HTTP proxy, e.g.: 80, 3128

Web Shield will now monitor the communication between the browser and the proxy server. If the proxy server is running on your PC (localhost), also clear the "Ignore local communication" checkbox.

On Win98/ME:

1. Open the file avast4.ini located in C:\PROGRAM FILES\ALWIL SOFTWARE\AVAST4\DATA in Notepad.
2. Find the section [WebScanner]
3. Add the following two lines into this section:

UpstreamProxyHost=proxy.myisp.net
UpstreamProxyPort=3128

(replacing the proxy.myisp.net and 3128 values with the appropriate details - i.e. current browser's proxy settings).

4. Restart the Web Shield provider – terminate and then start again
5. Configure your browser to use Web Shield as its proxy (server: localhost, port: 12080).

Web Shield will now forward all connections from the browser to your ISP proxy server. Incoming documents will be scanned during their download from the ISP proxy.
