hm yes - if that is the case then my system is still open like anything - at least meanwhile I installed https://www.spyshelter.com to see if anything dubious is going on - but probably I will have to change to a newly setup system - at least remaining cryptos are on a ledger now and 2FA backup codes are on paper only
I'm sorry for your loss, this was an expensive paid price of your negligence + extremely poor attitude to safety. As you have noticed, for part of the stolen coins are very likely responsible BCD and BTCP fake wallets - when you put your seed there, all BTC and BCH (if they shared same seed) are very easily stolen.
If you think you've been targeted attacked, ask yourself who all know you had that kind of coins in your possession ? Family, friends, acquaintances, girlfriend...
In any case you should all report to the police, this is big money and you do not have to reconcile that it's all over and money lost. Too bad that you did not use HW before, when it is obvious that you have it in possession.
