Problem with CVSWEB interference

[Theo Wolfs]

Hello,

Hopely you can help me with a problem,

Since a few days, every time I open IE6 on my windows2000 machine, the browser opens with the message  "downloading file /downloading in progress from  breedband telenet[1]"
Than comes the question : Open or save the file or Cancel. Whatever I choose, IE6 will shut down, and there's no way to surf. Re-instaling IE6 didn't help. Cleaning up all related cache and folders does not help.
I managed to open the file, and it pointed to CVSWEB. 

/* PAC FILE: VERSION MANAGEMENT WITH CVS

function FindProxyForURL(url, host)
{
  // Direct connections to non-FQDN hosts
  if (isPlainHostName(host)) {
      return "DIRECT";
  }

  // Direct connections to local subnets
  if (isInNet(host, "195.130.128.0", "255.255.224.0") ||
      isInNet(host, "212.123.0.0"  , "255.255.224.0") ||
      isInNet(host, "213.224.0.0"  , "255.255.0.0"  ) ||
      isInNet(host, "213.118.0.0"  , "255.254.0.0") ||
      isInNet(host, "81.82.0.0"    , "255.254.0.0") ||
      isInNet(host, "10.0.0.0"    , "255.0.0.0") ||
      isInNet(host, "172.16.0.0"    , "255.240.0.0") ||
      isInNet(host, "192.168.0.0"    , "255.255.0.0") ||
      isInNet(host, "127.0.0.0"    , "255.255.255.0")) {
      if (host != "gamesproxy.telenet-ops.be") {
      return "DIRECT"; }
  }

  //Microsoft does not understand DIRECT
  //URLs that have microsoft in them go via proxies
  if (shExpMatch(url, "*microsoft*")) {
      return "PROXY proxy.telenet.be:8080;"
        + "PROXY proxybu1.telenet.be:8080;"
        + "PROXY proxybu2.telenet.be:8080";
  }

  // HTTPS goes straight.
  if (shExpMatch(url, "https:*")) {
      return "DIRECT";
  }

  // proxy servers are now divided in two backup groups
  return "PROXY proxy.telenet.be:8080;"
        + "PROXY proxybu1.telenet.be:8080;"
        + "PROXY proxybu2.telenet.be:8080";

}
 
If I change my Start-up page of IE6 into per example www.yahoo.com , the lines in the file change also and point to the yahoo site.

What is this, how did it happened, and what must I do to get rid of this. 

Thank you,
