Remove no longer used NetNanny and ESET anti-virus error

Reland of http://codereview.chromium.org/10877025/.  Accidentally included other code in the CL when manually landing after the CQ got stuck, so had to revert (See http://codereview.chromium.org/10880048/)

Remove no longer used NetNanny and ESET anti-virus error
strings and ESET error code.

Hmm...Thought TBR would allow a land.  Thakis:  Could you sign off on this
again?  It's the same CL as before, I was just really careless when I landed it
last time, so had to revert.

Thanks.

It does, but you wrote TRR instead of TBR, so fix that maybe :-) LGTM anyway.
