Recurring threat being detected everytime I load a page

Hey Guys,

I am in a bit of a pickle… I have had avast for the past 3 years and havent had any issues…

About 3 days ago, avast started blocking threats on every page that I would open on Mozilla, it said firefox.exe was the problematic file so I deleted it and started using chrome… everytime I open a webpage I get the following threat (attached file)…

I dont know how to get rid of it, I have tried running various malware removal programs but nothing is helping… Please advise on what to do.

Cheers

follow guide and attach the requested logs (not copy and paste) http://forum.avast.com/index.php?topic=53253.0

run in order listed
AdwCleaner / Malwarebytes / OTL / aswMBR

when done removal experts will be notified and check the logs for infections…

if trouble running any of the Tools, try run from safe mode…
