Tom, we really need the full AVG log and full Ewido log. Even though you said items were cleaned or quarantined we need to see exactly what they were and their exact locations. In some instances, even though the programs have cleaned the offending files or programs there could be another step of manual cleaning required to be certain that everything is removed. Often times these nasty items create new files, which by name may look like something else and therefore not picked up by the scans and a manual search must be done.
Even though you feel the file is too large please try to post it. If the size is the problem then use a zip program to post them or copy/paste them in a thread. Do them one post at a time if you feel better about it. Generally we can receive most logs. But we do need to see the complete logs.
Also, your HiJackThis log shows that you have used msconfig to disable some start up programs. We need to see those IN the log. Please go back in and re-enable all those you have disabled via msconfig and run a new HJT scan.
