Nginx is a web server, and will provide a route for someone to access your machine using a web browser. If you connect to http://localhost, you may well get a web page. Note that Nginx may be using a non-standard TCP/IP port, in which case you will need to append the port number to the URL (e.g. http://localhost:8080). Nginx is probably running as a Windows service with admin privileges. You should be able to disable the service from the control panel, although there is nothing to stop some other bit of malware from re-enabling it. You need to find out where nginx.com is located on your disk drive. Deleting it (or re-naming it) may well solve your problem (unless some other program is waiting for such an event to re-install it). Obviously, the best course of action is to find out what software installed and activated Nginx in the first place. Have you installed any software that provides a web interface? There is the possibility that Nginx is running legitimately and is not the cause of your problem, but some software my be using an infected version.
Nginx is a know attack vector, and since it is a legitimate program (and may not contain a virus), it will be ignored by anti-virus programs. However, it can still be used by remote scripts to access your computer. Google Nginx Virus

'I have no wisdom,' he told her.
'Your experiences, then?'
'They have been trivial, uninteresting, and full of error.'
