Everything could happen in an instant it's your choice isn't it? If you rather leave it be or be paranoid and make sure your money is safe.
My advice relocate all your money in another wallet and make a new one in your ledger wallet just to make safe. I know you will lose money from relocating all your money because of fees but would you rather lose all your money in an instant.

Based on the comments The odds are in your side though you should be calm and pick what's best for you if you think my advice is not worth it then ignore me and pick whatever means necessary.
