Just out of curiousity, I tried MyD & Astlog on NIS09.
With NIS09 on default settings, I downloaded MyDefrag-v4.2.5.exe without problem, installed without problem, executed without problem.
With NIS09 on default, I managed to download astlog.zip. Upon unzipping, autoprotect removed the .exe (not recoverable from quarantine) and two other files, leaving an empty astlog folder. Upon scanning astlog.zip, the .exe was removed from the zip.
With NIS09 Sonar Advanced Protection off, autoprotect still removed the .exe from the zip file, and also removed everything from the extracted folder.
Only when I had added "AsteriskLogger" into Signature Exclusions, did NIS09 let me extract without removal, and scan without threat detected. The only thing I did not do is to try to execute the program.
Apparently, Symantec categorized this as "Potentially Unwanted App" here:

I think this is not a FP but a concern from a security point of view (that's why it is labelled "potentially unwanted"). If you let your friends use your computer, you can recover their passwords for whatsoever intentions you might have. Nirsoft and other program developers might have good intentions, but it is like a knife, you can use it for good, and you can use it for bad.
I'm sure I'd like Norton to ask me: "This is a Potentially Unwanted App. Do you want to continue...? Click here for more info..."
