What can I do about the sponsorship virus?

I keep getting these popup windows named Qtrax and or sponsorship. They pop up all the time and are a real pain. I’ve looked around at different sites that claim they have a fix but it usually requires downloading something which is probably where I got this infection. Has anyone else ever run across this and if so, how did you get rid of it? I have Avast downloaded and run updates twice a week but when I run a scan it never comes up with anything. I also use SUPERAntiSpyware Pro and it also does not pick it up. I run an XP machine that is loaded with Firefox and Chrome but use Firefox 99% of the time.

I was wondering if the Avast support team is working on a fix for this?

This is probably a firefox addon

Please download Junkware Removal Tool to your desktop.

[]Right-mouse click JRT.exe and select “Run as Administrator” the tool will open and start scanning your system
[
]please be patient as this can take a while to complete depending on your system’s specifications
[]On completion, a log (JRT.txt) is saved to your desktop and will automatically open.

This is not related to Firefox. I use Chrome and IE, and only IE is infected with this virus. Avast does not recognize or remove it. I am using the latest Avast Internet Security v130828-0 updated 8/23/2013.
Will Avast be putting a fix in for this?

Lets have a look see this is in all probability classified as a PUP
