i have used nirsoft utilities (along with sysinternals) for years. up until now (2013) it simply one of the best. no sign of it to become junk/rotten/ad-ware like some others. though i guess it does acceptable page view ad (who doesn't do that today anyway?).
some (questionable) scanners might give a false alert, that's ok considering the nature of nirsoft's utilitities.
anyone here tries to discredit nirsoft while promoting his site almost certainly is scammer.
This web site belongs to Nir Sofer, a generous genius who codes numerous and very useful small-footprint standalone tools and gives them away for free.
His tools contain no malware, spyware, adware, or nagware, and are listed on the best freeware sites. Because some tools, such as his registry search tool, are designed to provide users with info about low-level system components, they may trigger false detections some third party security software which could be called "Nir-Sofer-ignorant". Some major brands of security software easily recognize his tools without false detections.
No trouble found.
Produkey is an awesome program. Yes, you need to disable your antivirus to use it, but that is because it uses script that is used in certain instances malware. This "malicious" script is not malicious if used in a lawful manner, as Produkey was intended. I can't begin to count the number of discs I've lost/ damaged/someone stole from me (shit happens), and the amount of times I've gotten calls to repair a program on a used laptop with no available documentation. Produkey rules! IT WONT HURT YOUR COMPUTER!!!!
