Thanks but that's not quite the same as I am not getting a 404 message. What I did was to delete all the cache, cookies, and now it's OK.

Happened again today, the only solution seems to be clearing the cache. I notice others are complaining of the same problem too and I wonder what it is. My virus scan turns up nothing and everything else seems to be running OK.

Thanks cor-el, the solution at the second link, https://support.mozilla.org/questions/811399 worked for me.

Thanks I see Anti phishing domain advisory but I don't see a Panda program. Do I uninstall antiphishing domain advisory?

D.

I spoke too soon. Removing the antiphishing domain advisory did not eliminate the "welcome to nginx" message on some pages. If I clear all browser cache and restart firefox, I can go to the sites in question, so that is a temporary fix, but eventually, I still see the nginx message crop up. I used the ccleaner registry cleaner yesterday and will see if that helps, but I suspect my system still has something hidden on it somewhere. this all came about when I loaded a free driver scanner software (the kind that tells me what drivers I need for my hardware). If anyone ever needs to backup their drivers, a good free program that has no hidden issues is a program called double driver.

I found some more folders in my Application Data folders that were related to the driver scanner software and I removed those. I also had to use a file shatter program to remove a driver updater file from my local settings/temp folder since it would not otherwise delete by normal means. It has been about a day and I have not seen the nginx message return. I think the "ccleaner" windows registry cleaner program helped also.

I thought this article was also helpful. http://guides.yoosecurity.com/hijacked-by-welcome-to-nginx-virus-removal-step-by-step/

I have this problem too and it sounds like the virus that vsjogger gave the link to. The article told how to get rid of it on Internet Explorer, but not Firefox. It was to complicated for me anyway, but if anyone can tell me in simple terms how to get rid of it I would be most appreciative.

I didn't do anything with proxies in my browser. I think the main things I did to get rid of this (I have not seen further problems since my last post) was to:

1. Use CTRL-Alt-Delete to bring up the task manager. Then click the Processes  tab and end the processes titled "uninstall.exe" and "securitycenter.exe"
2. Use the Windows Explorer to find these on the C:\ drive and delete them:
    %appdata%\random.exe
    %Windows%\system32\[random].exe
    %Documents and Settings%\[UserName]\Application Data\[random]\
3. There are some registry keys to remove, but all I did was download the free CCleaner software (just google it), and ran that to clean my registry.
 4. In my case, there were also some files related to the driver scanning software  (original culprit) that I found in my program files folder and local 

settings/application data folders. I deleted those with a file shatter program. I think there was something in my temp folder also and I had to shatter that because it would not go into the recycle bin via the delete key.

These steps worked for me and are not very complicated if you work through them.
