I was running Adaware Ver 8.1. I recently purchased a Western Digital My Book External Hard drive. Adaware prevented the installation of the HD software. It kept identifying JSTART.EXE as some type of trojan horse. I had to disable Adaware to get the software loaded but, after reactivation, it prevented any files from being backed up. I could not figure out how to tell it to allow JSTART.EXE. Finally, I removed Adaware from my PC.
