Hi Andrei. :-)
My advices to improve your program:
1) use a date system like 07 Oct 2018. Like you saw, it could be misunderstood.
2) add the usual buttons: maximize, minimize, minimize to tray, and close.
3) make it portable, if possible.
4) malware engine right now says 29 scans: I would be interested on the items it scanned.
5) what does happen when the software finds something? It will give me a choice? Or it will block on its own?
