Internet Explorer Issue

[Jaypeg]

I use IE 6.something, as of late I can't enter an address in the address bar without using www first (meaning I have to include www in the address when I used to be able to leave it out). I used to be able to, but no more, now I get this error:

HTTP Error - Access Blocked

None of my software has been able to detect any kind of spyware or virus. I am using McAfee Security Center (Paid) and Webroots Spysweeper all to no avail. Anyone experience anything like this before? Could it be a security setting in IE, or perhaps a preference setting?

Thanks for any help.

Only thing I know that would do that is spyware. Try to scan with housecall, spybot, adaware and MS antispyware. Then post a hijackthis log.
