Ran AVG and Avast! several times and they keep finding malware/trojans and I keep killing them, but they just repropagate or bring in new types. Tried advise of running several other tools, but can't quite put it to rest. Created a complete back up of system in beginning, burned an AVG self booting rescue CD and USB stick. Tried to manually remove threats, but obviously missed something. Finally, ran Combofix and now not sure what to do next to make sure these threats are taken care of. Please take a look and advise.
