How to block endless pop ups

Hi
I m running Windows 7 Ultimate and using Firefox 24 browser. I have been having so many problems with pop ups that I can hardly use my computer. I have some knowledge of how to deal with them but nothing seems to work. I run regular anti virus scans and have recently run Super AntiSpyware, Lavasoft's Ad-Aware, Malwarebytes' Anti-Malware, and SpyBot but nothing fixes the problem. I keep getting "Visitor Surveys" one after another, "about blank" links in my address bar, unrequested links all over the screen and most annoying of all a pop up link right next to a legitimate link that I really do want to clink on. Whatever I do it won't let me click on the legitimate link.
Can anyone help me sort this out.
Many thanks
Matthew

I've come across this before with pop-ups. I would download a program called "ComboFix" from the link below. Be sure to close ALL programs and run this program. Do not use your computer while the ComboFix utility is running, when it completes it will want to restart your computer and continue scanning, this process could take around 10 minutes or more depending on how bad your computer is.

Stop using Firefox. Firefox is host to all of malware and poups and spyware addins.


I had to unistall Firefix due to the exact same issue.

First of all check the add remove program for any unwanted application and uninstall them, after that use below settings to stop pop-ups in mozilla.

Have you tried Microsoft anti malware?  It seems to work every time.  When you run it you have two options, the quick or the full scan.  Don't bother with the quick.  It will take 3 to 4 hours.  I have always had success with it http://www.microsoft.com/security/pc-security/malware-removal.aspx
Scan with Adwcleaner:

Then:

Use an addblock plus (like) addon; or a program such as Ad Muncher:

Hi guys
Many thanks for all your suggestions. I will work through them all and am running ComboFix at present. What browser would you recommend? I always thought Firefox was one of the best.
Thanks
Matthew
The browser has certainly been hijacked. Even though it will be a great deal of work, I second the notion of wiping and reinstalling Windows. Any fix at this point, is bound to be temporary as the infection is probably lying at a deeper level. For remediation, I like Windows Defender Offline. This creates a USB boot key and runs the MS anti-malware from the key.

Browser usage is a matter of choice. I have all three of the major types installed on my system, though I prefer Chrome for the Google services integration.
The browser is not the problem.  No AV, free junk AV, ignoring AV warnings is what gets computers infected; along with downloading junk without doing an AV scan, and visiting sites known to be infected.  

Safe browsing is just like safe sex.  Use a condom (high quality AV) and lock your computer down so it does not let you do stupid things.

Well, in "[Safe] s.x" people are not attacking you without your knowledge. ;-)
Hi guys
Just to let you know I have run ComboFix which did remove several files. I am now running Microsoft Malicious Software Removal Tool which I think might take some time as I have a lot of files and hard drives.
I will keep you informed as soon as it finishes and follow your other suggestions.
Thanks
Matthew
Well, in "[Safe] s.x" people are not attacking you without your knowledge.

People don't infect you; the viruses they carry do.
Websites and applications don't infect your computer, the viruses and trojans they carry do. :^)

Well, people don't enter your computer; they use virii (and other malware) deliberatley to enter your computer and infect it -- without your knowledge.

In "s.x" entering is there, but virii are (without anyone's knowledge) not used as tools to deliberately infect you.

Well, we are "hijacking" this thread, and thus we are virii also. ;-)

Cheers.  :-)
Hi guys
Windows Malicious Software Removal tool is still running. It has been going for nearly 30 hours and is probably only about 20% complete. Zero files are infected so far and I'm wondering if I should continue?
Unfortunately I am now having problems with this computer which keeps crashing and I'm going to raise another question now before it crashes again.
Thanks
Matthew
That's too bad.  30 hours sounds like 26 hours too long. It seems like the advice above is to wipe everything clean and start over.
Hi everyone
I guess reinstalling Windows from scratch means reinstalling all my programs and files as well from scratch? Is there any other simpler way of resolving this problem?
Many thanks
Matthew
EDIT: *** Whoops, you said it was the Malicious Software Removal Tool.  I misread this as Microsoft Security Essentials ***

Did you schedule the scan to start and run overnight, or did you just open the Security Essentials interface and click the "scan now" button?

The reason I ask is that by default, a scheduled scan is set to limit processor usage to 50%.  30 hours would still be extraordinary even at only 50% CPU usage, unless of course this is a really large hard drive that is packed with millions of zipped or compressed files that can take a while to scan internally.

You can mitigate some of the aggravation in reinstalling Windows by first gathering up and saving out as many of the program settings (note: not actually the programs, only their settings) and user files as is possible, and then import them after reinstalling Windows.  To do this you can use the Windows Easy Transfer.  It is still a real pain in the neck though, and probably worth leaving this option as a last ditch one.
Hi
Thanks everyone for all your help and suggestions. It has been a learning journey. I'm going to live with the problem for the present until I up grade my PC completely.
I will try to allocate points fairly.
Matthew
I agree with aadih to try all possible solutions but in the end I think adriaanvw is probably right in saying that ultimately a complete Windows new install is necessary.
Great.  (What matters in the end is:) You got it working. :-)
