Welcome to nginx!

Hi,

lately Firefox hangs or redirects me to a blank page with only the text "Welcome to nginx!". This seems to be especially true with google, youtube, and maybe any page that is visited frequently. I am running Avira free ver 12.0.0.1125. I have tried just about any virus removal tool (Avira Free Antivirus, Malwarebytes, Kaspersky rescue cd, Fsecure rescue cd, Tdsskiller...) I have been able to find, but nothing seems to help. How can I get rid of it?

Hi markkuhu,

First of all, please check your TCP/IP settings and verify DNS servers configuration. They must match the valid one (suggested by your ISP).

Hi Farger,

I am using ADSL, and both the IP-address and DNS-server address are provided automatically by the ADSL-box/service provider. Most of the time internet and most of the web sites seem to be working OK. This set up has been there for a while and I am not aware of any changes in it. Is this what you asked?

Hi,

Yes. I assume that now you don't get that warning, am I right?

Hi,

unfortunately that is not the case.

My understanding is that there is something (a trojan?) that hijacks the browser
and pretends to be pretty similar to the "legal" nginx. There are a lot of recent questions about this in the web, but nobody seems to have the answers.

Hi,
just found this:

http://nginx.org/en/docs/welcome_nginx_facebook.html

This seems to apply to me and others.

Yeap. In most cases it is enough to check TCP/IP settings and verify DNS servers configuration and adjust them to the correct one because very often fake settings are inserted, for example 134.255.241.122

So, if you still receive "Welcome to nginx!", then you can follow the instructions from the link you have posted. If you don't get the warning anymore, please tell me this and we will make some logs to verify that everything is ok.

Hi,

Please resubmit virusinfo_syscure.zip and virusinfo_syscheck.zip to any other file hosting service, e.g. filefactory because I need the logs "as it is" which is not possible with the google docs.

P.S. I have posted the link to the latest avz version.

Hi,

1. all but the last item seem to be legitimate. As for the last item- there are some additional similar .bat plus one .ini -files that I know nothing of. Judging by the file date they have been around for some time. They are from the year 2008.

2. Not knowingly

3. done

4. done

Submit winstart.bat to virustotal and post back the result.

So, if you don't know these entries and you didn't set these settings

R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer = 127.0.0.1:8118
R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = localhost:6464;*.local


then open HJT -> Do a system scan only -> select those items and press Fix checked!

Hi,
at the moment it is OK, but the way it has been behaving is that it has it's good moments and bad moments. I would not close this today. What do you think - we give it two days and I will be informing you after that?

Hi Farger,

this one seems to solved. I have experienced zero redirections and also the sluggishness to get to a site seems to have gone! Great job!

Thank you very much,
Markku
