With one trusted men, I discussed this my problem on the telegram, he looked at my wallet.dat and said that BTX had gone to another address and it is impossible to restore them, only I still do not understand how, possibly malicious software...
It's unlikely you'll get it back, but if you own more crypto, you should check your computer for malware, and generally consider a security check for your holdings.
Look at your system logs - maybe there's a record of something unusual.
Thanks for the advice, all I can do is update the antivirus...
It may be not enough. You should try to determine what happened.
Was your wallet file secured with password? If so, it must have been discovered somehow.
Try to check logs for network activity, suspicious programs/services, unusual behaviour like unexpected mouse movements, keys, etc.
If you hold more crypto, don't use that machine until it's clean.
