This is most likely a firewall issue. You have a security software of some sorts that is denying you access to those websites. Or you could possibly be infected with malware. I would recommend Malware Antibytes to remove infections.

1. Make sure you have no viruses in your system. Check it by strong tool, for example AVP tool http://support.kaspersky.com/viruses/avptool2011?level=2
Switch off your antivirus before scan
2. Check or set to default your internet firewall settings.
3. Delete the chrome and crashreport subfolders from C:\Users\%your_name%\AppData\Local\Google\
4. Install chrome anew

Scan your computer for malware/viruses and remove anything harmful you find (if anything)
Clear cookies.
Make sure Google Chrome is allowed by your antivirus and/or firewall.

Google chrome gives me this error:
Error 102 (net::ERR_CONNECTION_REFUSED): Unknown error.

Firefox gives me this error:
Failed to connect. The connection was refused when attempting to contact www.google.com.

IE gives me this error:

Internet Explorer cannot display the webpage

This problem can be caused by a variety of issues, including:

Internet connectivity has been lost.
The website is temporarily unavailable.
The Domain Name Server (DNS) is not reachable.
The Domain Name Server (DNS) does not have a listing for the website's domain.
There might be a typing error in the address.
If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section.

clear your cookies. check for a virus. check firewall settings so that google chrome is allowed. if web pages don't come up in other browsers then the error refers to an internet connection error. reset your router.

Try to download firefox browser /it could be a browser issue.

Error 102 (net::ERR_CONNECTION_REFUSED): Unknown error.

Hi
If you are using the google chrome browser, there are a number of issues that would cause that error.
I would try testing with another browser to see if you can connect. ( IE, firefox, opera.)
if you can get to the net with another browser, google has posted this info.
