Looks like there are some new variants of the naughty FFSearcher trojan with its nasty rootkit abilities and alternate data streams jiggery pokery. Unhackme seems to be effective to start the removal process with SpyDllRemover and MBAM helping out. New variants seem to close every thing down though so you can't run many tools that would prove useful and because it stores itself in an ADS even scanning from live environment disk doesn't necessarily show it up.
The bugger.
