In hopes of making my two computers as safe as can be I went ahead and removed the various files that AdwCleaner detected in a scan. However, because I had issues with my computer's hardrive becoming corrupt recently, I'm worried that some of the registry files that were deleted might in fact be necessary ones. Can someone please let me know if this is the case? I've posted the content of the log below. Any help would be greatly appreciated, as I just want to make sure I won't encounter such costly problems again.
