My PC has been infected with a malware that opens pop-up to some ads, mostly in my native language (Persian) but from (wonderlandads.com), when I click on a link or in an input box in StackExchange websites. Interestingly, it just occurs for these websites and no other website! It occurs in both Firefox and IE

I scanned my computer with NOD32 7.0.2 , and some freeware malware scanner (kaspersky tools,...), but they couldn't find it. I reinstalled the Firefox and disabled startups but couldn't fix it.

What is the cause? and what can I do?

How it can hide itself from powerful antiviruses and anti-malware?

==============

Update It seems I could handle it by killing running processes and refreshing the firefox.

In this link, you can find the details about removing Wonderlandads pop-up malvare.

Briefly:

  • Kill running process by task manager (especially suspicious ones)
  • Uninstall recently installed programs (especially cracked and suspicious ones)
  • Disable suspicious programs from start up.
  • Reset your web browser.

As this pop-ups occurs only for the websites of StackExchange, I cleared the cache items related to *.stackexchage.com as it is in How can I clear a single site from the cache in Firefox?. Now the problem has been resolved without any restart or killing a process. Then I guess some client-side scripts were infected and by removing them you can solve the problem.
