Nothing wrong with that Try having over 180+ wallets. I trade and I mine.
I would look though your system for any processes that look out of place or you do not know of. 2nd get malwarebytes to scan system. If you find processes n task manager you cant close opend by username then ull have to sieve though and remove them manually. Now with you saying they where encrypted then this sounds different if your wallet is password protected then it sound more like you had some key logger and other infections on your system than just a wallet stealer as if encrypted they would still need the password.
