well, guys - u might b right… 
but as we don’t know 4 shure, we should try 2 help, if possible… ;D
yeah, but not by searching a needle in a hay-stack. And BTW it may be too complicated for him. The firewire e.g. is just the hardware in his device-manager. He is not using it, for sure.
I hope he will send a hijackthis log, that lights up at least a little on the sw-side.
right, let’s wait 4 that one…

By the way, a noob question: am I not displaying any too private info in the log? I mean…this is a public forum and I did not find a way to send a private message…
You are running Spybot S&D…? That right?
Disable Teatimer in Spybot.
Its more a hazard than a help - and may be the cause.
Maybe Spybot S&D is the problem… first guess. Can you disable it totally, just to see? Better even uninstall - and reinstall afterwards if avast should work then.
Actually…no. It is not even installed on the computer anymore (I recall it has been used long ago)
I cannot even find the file in “Program files”
(by the way, can you please tell me if there is no problem with the log beeing on a public internet page? :p)
No prob. It’s very common in av-forums.
Spybot is still in your startups (in the registry) :
O4 - HKCU..\Run: [SpybotSD TeaTimer] C:\Program Files\Spybot - Search & Destroy\TeaTimer.exe
Do you have any registry cleaner, like CCleaner, TuneUp or GlaryUtilities free?
Clean the registry with it.
Well. It works now!!! Thanks so much for your help. Hope it is not temporary but it doesnt seem so!
Have a nice evening
STOP!
What did you do before it started working?
We rely on feedback here!
+1
Hello,
First, do not worry I will not disappear as soon as the problem is fixed.
Unfortunately it is not fixed yet 
I had installed CCleaner and cleaned 1,7 GO (sounds huge) and then it worked. Rebooted. Worked again. The day after, it does not work anymore
GO? What is that?
The problem is back? :o
Would you mind and give a short description of the problem again? Sorry for the inconvenience…
We’ll try our best! I think there will be not too much moderator support until Tuesday, after all, it’s Easter time. ;D
One stupid thought…: is your date/time on your PC set correctly?
Giga octet
Ok so here is an up to date description :
When Avast web agent is off. I have access to internet without any problem
When Avast web agent is on. I apparently have from time to time access to the internet (that’s why it worked after CClean) but most of the time connection is not working. When I ask to check what could be wrong with the connection (the web browser automatically ask if I want) it says everything is ok
Okay… I remember we did this already? http://forum.avast.com/index.php?topic=57443.msg484431#msg484431
Would you mind checking it again, just to be sure?
BTW: what is Giga Octet?
L’octet - c’est francais pour “byte”?
IIRC, one byte is 8 bits…
;D
How can “byte” be ambiguous…? (Referring to wikipedia)
http://www.wordreference.com/fren/octet
So I guess yes
I checked and the TEMP folder exist in C:\Windows
I checked registry and HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
has values TEMP and TMP
By the way, I am going to be slower answering since now I am back in Paris and my relative is in Marseille so I have to explain to him by phone and have him do what you ask me since he does not speak english. But please be so kind to keep helping, I will answer as fast as possible.
