Firefox Streaming problem ++

i have problems with my firefox.it's the newer version.it shuts down immediately when i try to open a video through the browser,or even live radio.(though i can watch videos at youtube for example).same thing with opera browser.in addition my internet explorer shuts down immediately when i open it,and windows live messenger shuts down when i log in, in 1 second.(though trillian works fine).
i have windows xp,updated constantly, avast antivirus and zonealarm pro firewall.through zonealarm i let every traffic of firefox.
please help me.don't know what to do 4 months now.

 

Done all the steps but two. Meaning the online tests as thus being impossible, considering that part of the problem is ie crashish right after loading. Also wasn't able to use Windows Defender, so in place of that there is the CounterSpy log and the other two of course.

EDIT: Forgot to say the obvious, being the problem still persists.

 

Please post the other logs. We need a HijackThis log, An activescan log and a bitdefender log.

 

As i said before inability to run ie and msn is part of the problem making the retrieval of active scan and bitdefender logs impossible to my knowledge. I'm going to post hijackthis log as soon as possible though.

Either way thank you for taking the time to look into my problem.

 

Here is the hijack-this log.

thanx in advance.

 

Why do you have some programs installed on H: and some on c:

Your AV really would be better off installed on your system drive.

Your HJT Log is clean (well pretty much... see below)

The items counterspy found which are what I assume tim was refering to when he said you had malware arn't really that bad, DAP and Weathercast should really be removed but arn't causing the issue here.

I don't think the problem here is really malware related, I suggest you remove all your toolbars and bhos such as Google Toolbar, Yahoo Toolbar, DAP, MSN etc and see if this helps IE, other than that I suggest you head back to the software forum.
