403 forbidden Apache

Imported from previous forum

when I input ‘www.fixprotocol.org’ site in IExplorer 8, i get following apache error:

Forbidden
You don’t have permission to access / on this server.

Apache/1.3.35 Server at fixprotocol.org Port 80

Even if i reinstalled IE 8, no change.
Other machines in my office can access this site from within IE8 but only my machine cannot access.
Please note that i easily access this site through other browsers like Chrome, Firefox

There are some IE plugins that we’ve had to block (because they download and pre-cache every link on a page, including large documents from our database). Can you check and see if you have FDM, EmailSiphon, or EmailWolf installed?
