Examing logs created by malware removal tools

Your best resource is the thousands of posts in this forum.

BitDefender and Panda are rather self explanatory in most case however you still need to know the difference between valid detections and false detections and that comes with significant experience over a period of time.

We don't have time to really explain GetRunKey and ShowNew to you. In short GetRunKey shows lots of registry keys (not necessarily bad) and potentially bad files associated with certain infections. ShowNew dumps out important areas of the file system that may be used by malware. ShowNew also prints and uninstall program list so you can see if any malware is installed. You need to have a good understanding of ALL Windows OS's, the file systems, and the registry to understand what they are being used for. Also you need to again be able to distinguish between what is valid and what is not valid and that also comes with significant experience.

Reading the threads and reading the logs and seeing what is fixed and not fixed will teach you a lot.
