Hi all.
Wrote a little utility for myself. Put it on
https://sourceforge.net/projects/filechangeswatcher/
Sourceforge says that he found virus signature.

(infected: Gen:Heur.MSIL.Krypt.4)
Of the functions use a FileSystemWatcher, there is a function that prescribes a program in startup user (but is invoked as a separate item on the menu). What's the catch?
PS
Colleagues, so stupid palitsya I wouldn't. A program grind is very long and it's a shame that after so much pain it is taken for the virus. Work Kaspersky anti-virus is silent.
What works:
Just a little service for routine operations.
It is clear that the idea is to monitor everything is not new. Antiviruses in this regard is simply out of reach.
BUT!
Although I am a programmer, but if you consider me as a user, I have a archive files, and quite extensive. It is located on the portable drive. The volume of this archive more terabytes. Directory - a few hundred. During the day I have this "archive" is sufficiently active work: - upload the image icon in the project to save the attachment from the letter in a certain project/directory, download the fiddler session to a file, etc. ie for such a file operation with files - a lot. And if you download from the Internet in Chrome or Mozilla appear useful button "open folder with downloaded file," then a heap of other programs of such a function at all. Imagine that you have just Notepad saved the file deep in the hierarchy and then the face in question... and... where is he??? Now just to solve the question "where did I just save the file?". )
That monitors:
Monitors only the specified directory (with the possibility to add exceptions) and only specified extensions (to not do a popup at all). For example, if the project is grunt or maven, that message can be many. Put an exception on the build directories. - ima.Halvorson commented on July 9th 19 at 11:38
In principle, they can be discussed separately in terms of development and promotion of Your product on the market. - Kyleigh_Hills commented on July 9th 19 at 11:44
It is better to write something simple and need to sell for very cheap.
Here is a very good example (I bought): https://www.abbyy.com/ru-ru/screenshot-reader/ 490r (a great balance between the income and purchasing power for this functionality) - Kyleigh_Hills commented on July 9th 19 at 11:50
