I confirm that the wallet file contains a virus - a trojan! Trojan-PSW this Password-Stealing-Ware (program to steal logins/passwords). I would never install a program on my computer that confirms the presence of a trojan by a large number of different antivirus programs.
Olkah, here link to RU Wiki about this virus:
https://ru.wikipedia.org/wiki/Trojan-PSWThanks VladimirN, I will add this information in my first post.
I think the new wallet has not been detected by the virus, I tried to install it and it works normally, whether my anti-virus is outdated or there has been a change in wallet NBC.
