Nginx error (Welcome to nginx!)
The Nginx error (Welcome to nginx!) is a generic error page that's used by Nginx (a reputable company with widely used open source web servers) for server-side errors that cause a failure to display the appropriate web content. By itself, the Nginx error page is harmless, but there are some attacks by browser-hijacking PC threats that result in a Nginx error landing page. If your browser is redirected to Nginx error pages without corresponding attempts on your part to load a Nginx-based site, such as Facebook, your machine may be infected by a browser hijacker. Because browser hijackers can also be security risks and may block your ability to access certain websites, you should remove them whenever you've noticed their symptoms, ideally by making use of a good anti-malware application to scan your PC.
Differentiating Between a Harmless Nginx Error and a Nginx Error Hijack
Because some Nginx errors are a byproduct of innocent server glitches that aren't indicative of any harm coming to your PC, SpywareRemove.com malware analysts recommend that you take a close look at the symptoms around a Nginx error before you panic and start launching security programs to analyze your PC. Normal Nginx error screens are shown when your attempt to load a Nginx-based website has failed due to server issues that are unrelated to your PC. If your browser is loading an outdated cache of a site that's been corrected at the same time, you may be able to load the website in question by deleting your browser's cache and restarting your browser. These types of helpful Nginx errors only happens when you try to load a Nginx site intentionally – such sites include Facebook and multiple entries in Alexa's database of the top one hundred sites on the web.
Sadly, a 'Welcome to Nginx!' error page can also be indicative of the presence of a browser hijacker or related PC threat on your computer. SpywareRemove.com malware researchers warn to pay attention to unwanted Nginx errors that appear without corresponding attempts to load Nginx sites since these occurrences is evidence of your browser being redirected to a site with malfunctioning content. Many browser hijackers can also be reconfigured to redirect your browser to several types of potentially hostile websites, and some many also change your web browser settings to make your online experience insecure (such as by enabling malicious scripts to launch without warnings or permission).
What to Do When Nginx Errors Keep Coming Around No Matter What Website You're Trying to Visit
