Following the advice in this and other sites, I have been able to remove, I think, the XP Home Security 2012 malware.
Used system restore to restore to a point prior to infection.
Installed and ran MBAM - removed some infections
Updated MBAM rules - removed some infections
Ran rkill.exe - stopped two processes (one was known U3 process from USB I am using to move files from good machine to infected machine)
Ran tdsskiller - removed one infection
Copied MBAM rules.ref and database.conf from good machine after new install and update on good machine
Ran MBAM again - removed one infection
Fixed hosts file
Removed and re-installed Tcp/ip
Still no network connectivity
