Unwanted music and advertisments playing on laptop

Ho there,

I have for the last for weeks had advertisment and music play on my computer randomly. The material is audio and plays without warning when am using either Firefox or IE.
My laptop is runing on a Windows XP Sp 3 and has Symantec Antivirus ver. 10.1.4.400.
I have aslo tried Spybot, Malwarebytes, Super Antiware, MS Windows Malicious Software Removal Tool, Norton Malware removal tool and none have been able to remove or stop the audio playing.
Can you please help?

Hello bwaise,

If you would like someone to take a look at the system please see this FAQ "BEFORE you POST"(READ this Procedure BEFORE Requesting Assistance) which also includes instructions on posting a preliminary DDS log.

Then start a new topic in the Malware Removal Forum and a volunteer analyst will advise you when available.

Best regards. :)

Will do, thank you.
