83 Check if the "hosts" file doesn't contain entries other
84 than "127.0.0.1 localhost", and if so &#8212; if these entries are for
85 the web site you're trying to reach and instead you're seeing a
86 wrong web site. The "hosts" files is located in
87 C:\WINDOWS\system32\drivers\etc directory. Typically there should
88 be just one entry in it, for "127.0.0.1 localhost", that's it. The
89 "hosts" file can be viewed with your standard Notepad application.

93 Try to (temporarily) use Google Public DNS and see if
94 it fixes the problem. From Google's description of its Public DNS -
95 "Google Public DNS is a free, global Domain Name System (DNS)
96 resolution service,
97 that you can use as an alternative to your current DNS provider.
98 To try it out: Configure your network settings to use the IP
99 addresses 8.8.8.8 and 8.8.4.4 as your DNS servers. [..] By
100 using Google Public DNS you can: Speed up your browsing
101 experience. Improve your security. Get the results you expect
102 with absolutely no redirection."

106 Try to clear browser data (cache, cookies etc.), e.g. perform
107 "Clear Browsing Data (Chrome)". Caution: you may be

113 Try to check the plugins/extensions you've installed

119 If cleaning "hosts" file (when applicable), changing
120 DNS servers to Google Public DNS, or fixing your browser
121 configuration have helped, it might be that there's a malware
122 somewhere on your PC or around. It makes perfect sense then
123 to run a number of checks using your preferred
124 anti-virus/anti-malware tools.
