Google HTTP Server Request Error

I have a problem accessing any Google websites. I can visit Google.com without any issues. However, any other sites, such as Drive, Analytics etc. I cannot visit them. Basically this is what is happening. I type drive.google.com in the browser (I tried in all three major browsers i.e Chrome, Firefox and Safari). The error I get is attached as a image (Error is displayed in Chrome).

However, after that error, when I add HTTPS in front of the URL, it works fine. Now this happens only when I'm at my work. Though it doesn't happen for anyone else at work. The IT department doesn't know what is going on either since my laptop is the only one that is facing the issues. I'm running OX 10.9 Not sure if this is a virus or what. They have tried flushing the DNS and releasing and renewing IP. But nothing works. Any ideas on what it can be?
