Web Shield - Page stripping issue

Whenever I access the setting panel the web shield reset to high, and doesn’t stay on custom, so I have to make sure its on custom every time I need to click ‘ok’ instead of cancel. I need it set to custom to visit a certain site, and it seems to reset to high after I restart my computer. Continue on…

I’m also having an issue with the web shield causing www.verizonwireless.com not to redirect to http://www.verizonwireless.com/b2c/index.jsp in Firefox 1.02 When I make sure custom is selected with www.verizonwireless.com is ignored by the web shield I have no problem visiting the site with Firefox to have it be redirected to the proper page. Its stripping something from the page to cause this problem, putting it in the exclude doesn’t work, you have to put the address in the ignore field to be able to forward the site correctly.

Avast 4.6.623
XP Pro SP2

No problem with firefox (1.0.3 beta) and web shield enabled, your first link redirected fine.

Are you using any other security tools that might interfere or think there is something untoward with the auto redirect?

I have no other software proxies on the computer, other than alg.exe running ics in the background to share my dial-up connection… While making no changes to firefox, and just making sure that one website is ignored, there is no problem so I think I might just need to download the lastest avast, then uninstall/reinstall first. Also obviously terminating the web shield solves the same problem when its not set to custom.

I have no extensions, add-ons, etc… which change how a page is displayed other than plugins for common things like flash, quicktime, etc…

The version you have is the latest release version, there is however a pre-release 4.6.635 that I’m using, so I don’t know if that may be having a positive effect.

Did a search for 4.6.635 and this thread should be what you need to get the pre-release 635 - http://forum.avast.com/index.php?topic=12320.0

For me, on contrary, some pages does not redirect in IE or Maxthon, only in Firefox.
I know it should be a configuration of them there were blocking the access but I could not solve it… Only disabling WebShield.
I send the link to Lukas but he could not solve it for me…

Well, its at least good to know I’m not the only one who is seeing this kind of issue.

I have the same versions and service packs as you, and I’m seeing your issue too. IE redirects the page just fine, but Firefox 1.0.2 does not. Just sits there at “Waiting for…”. The only extension I have is AdBlock, which doesn’t make a difference even when disabled. I’ll have to experiment and see if I find anything.

I’ve noticed something is blocking FireFox from sending a second [SYN] packet to establish another connection so it can send the GET command to get the /b2c/index.jsp page.

With Avast disabled, FireFox sends some TCP packets to establish a connection, “SYN, SYN-ACK, ACK”, then requests the root page “GET /”, then you get back “302 Object moved”, then you send “ACK, FIN-ACK” to close the current connection, then you send another “SYN” to establish a new connection. Then you receive an “ACK” in acknowledge to the previous “FIN-ACK”. Then the connection handshake resumes and it sends “GET /b2c/index.jsp” etc…

But with Avast enabled, FireFox gets the “302”, then sends “ACK, FIN-ACK”, then receives the final “ACK” acknowledgment of the connection being closed. And that’s it, it just stops.

Using IE though, with Avast enabled, the second [SYN] packet is sent for the next connection handshake so the next GET command can be sent.

I tried disabling Pipelining in FireFox, but it had no effect.

EDIT: It seems like something external is blocking the 2nd SYN packet, since FireFox still swirls around thinking it’s going to get another connection. And when you add the web site to the “Ignore Address” line, or you disable WS, it works.

Here’s a packet log anyway.

UPDATE: Okie dokie… Fixed my problem by updating to the Avast beta version 4.6.635. This was probably the same issue a lot of other people had with other sites. BlitzenZeus, I suggest you give the latest beta a try. Thanks ALWIL!
