@Pelover, well, the seed is entered in a random order. So even if the computer is compromised the attacked still needs to try 24! combinations before cracking your password. So you will have enough time to create a new account as BurtW said.
In case you didn't catch the factorial operator, that's 6.2044840173323943936 × 10^23 combinations that an attacker has to try.
Even if they could try 1 quadrillion combinations per second, it would still take 20 years to exhaust every possibility.
Put another way, in order for an attacker to be able to find your seed within 10 minutes (during which time you should easily be able to transfer the coins to a different device), they would need to be able to try 10^21 (1 sextillion) combinations per second.
This assumes that the first 6.2044840173323943936 × 10^23 - 1 tested combinations are all incorrect, which is extremely unlikely. The probability of this happening is equal to having a correct guess in the first attempt
