The only way they can steal anything from any wallet is if they get a hold of the wallet.dat file. There is simply no other way. So at some point you get hacked, you may not even notice this, then when you have enough coins to steal they will sact. I think it makes sense to change your wallets, create a new ones on regular basis and transfer the coins around and always encrypt your wallets with 128bit+ passwords. You may not know when they put a keylogger on your PC if its not properly protected. I wouldn't be surprised if some Pool sites are infected with keylogger scrypts. They dont steal accounts maybe because its easier to just get into your wallet and steal your coins especially if you have weak passwords.
I bet they try to brute force the password, running their little evil scrypts to try to hack your password every day like you are running miner every day. So if password isn't changed like on weekly basis it is eventually hacked. As more often password changed as more complicated is to hack through your wallet as long as you don't have a keylogger. There are also programs out there that would populate the password field for you without you typing anything, in that case keyloggers won't help the hacker.
When you deal with something as open and raw as Internet you need to take 10x times stronger precautions than what you'd do for something like a house or a safe. Use different PCs every month (virtual machines, image, clone etc), transfer your coins around so they don't sit in the same wallet for weeks etc etc. Its hard to catch a log on the river with a strong current.
If you get rich and catch an eye of the hacker they will be tracinh you, hacking you, following your every online move until they get a hold of your wealth. Then they will vanish and you will never find them.
Sorry to hear that OP, but maybe your unfortunate problem can be a reminder for others to watch out, you are on the Internet!
