NirSoft, a collection of small and useful freeware utilities
I used these for years. Especially the Windows handles checker I found incredibly useful.That being said: When I recently recommended it to a friend he complained about virus scanner warnings. When we ran the tool through Virus Total we had a considerable amount of warnings and these were not only from the heuristic checkers.I have considerable trust in Nirsoft and maybe these warnings are wrong but on the other hand I have confidence in Virus Total too.
