I continue to get a popup called Customer-Poll Survey and also Google Survey.  I've been able to eliminate the audio part that included an alarm tone and woman's voice but cant eliminate the popup.  The introduction begins with, "Hi, my name is Lara Grace and we have selected you to participate in a 30 second survey about Customer-poll."
The second issue includes an address bar that sometimes comes up with www.ckntrk.com, sometimes with trknck.com, and sometimes with a third address beginning with m.  All include and a dialog box that says has varying claims including "the page at http//:pctrustalert.com says: Attention Comcast User!..." and tells me that firefox is running slow and to contact technical support, and something about my browser out of date and needing a critical security update. I then see another dialog box telling me I've chosen to open fl_setup.exe.
Next... I get something called "Savifier".  It's some sort of price comparison popup.  This needs to go.
I've tried multiple malware, adware and virus detectors.  Checked my firefox addons, etc.  I've exhausted my limited skill set and need some advanced help for a solution.  I use firefox and run Microsoft 7.
Suggestions?

First of all, you should check your host file and check if it is clean. If your host is modified by malware, there is a big chance you won't find any malware running in your system, how ever, having the host file modified by malware is a common method to spam your web browser and surfing experience with intrusive ADS and POP's up.
