WALMART SPOOF The following message has been sent to my cell phone twice.

Question

The first time was in January 2012 (approx.). The next time was on the date and time shown below. The first time it was sent I diligently replied to the web site show and waited for further instructions. Nothing happened, blank screen. So I refreshed the screen. Nothing, blank screen. I didn’t realize at the time that the desired effect had been achieved by the web site. A background program of some type had changed the way FIREFOX displays most web pages making them unusable to a large degree. It took me some weeks (about 6) to figure out how to regain my full browser functionality. But at that point I still had not put 2 and 2 together. When I got the text message again the other day (03/10/2012) I didn’t remember until after falling for the same trick again that it had happened before. As soon as I started surfing again I saw the damage done and then remembered that the same set of circumstance had happened before.

PLEASE HELP AND ALERT!
I do not remember exactly how far I had to go to repair FIREFOX the first time. I seem to recall starting with disabling add-ons. Then I just kept going one step further and testing until completely removing the browser and reinstalling it. I saved most user settings and favorites to reload afterwards but had to re install extensions and add-ons.
My routers NAT is always on. I always use NO-SCRIPT to screen web sites. SPYBOT and AVIRA were and are always active and updated weekly. I am fairly well versed in network security so am usually alert to frontal attacks, this one sneaked by to the back door.
It seems to remove or change the way html processes the gui removing the formatting and affects some of the button action commands.

Answer 1

It sounds like your computer may be infected with some sort of a virus / Malware.
I suggest the following resources:
[[Is my Firefox problem a result of malware |Is my Firefox problem a Result of Malware]] is a Mozilla Support article with some good tips on avoiding and fighting malware.
To double check your system is clean, do the following (Not official Mozilla advice, just good practice from personal experience)
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]
Download and Run TDSSKiller [http://support.kaspersky.com/faq/?qid=208283363 http://support.kaspersky.com/faq/?qid=208283363]
Download and Install Microsoft Security Essentials [http://windows.microsoft.com/en-US/windows/products/security-essentials http://windows.microsoft.com/en-US/windows/products/security-essentials] (not an official endorsement, but I personally recommend MSE as an awesome permanent anti-virus)
Double check for all Windows Updates.
If you are still having problems with Malware after that, I would recommend either [http://www.bleepingcomputer.com/virus-removal/ http://www.bleepingcomputer.com/virus-removal/], or having your computer cleaned by a professional.
After removing the virus, read [[Websites look wrong|Websites look wrong]] and see if that helps you.
