He probably installed malware which stole his private keys and uploaded it to someone who withdrew coins from the keys. I seriously doubt he would be able to recover the coins. I wonder what would happen if the person who stole the coins came forward and gave them back. Would your friend still give him 1 btc for recovering them? (it's not me btw but I was just wondering)

The attacker may have installed a key stroke logger. He would then just need to wait until the password was entered and he would have your wallet and password. It has been happening a lot lately it seems. M$ windows is terrible in terms of security - strongly suggest he uses Ubuntu or another flavour of Linux and does not download and install software he does not trust.

#1 It makes no sense to proxy this via you as your understanding is limited e.g. wallet is not the same as address. Your friend might also not share everything with you. In my experience even if you ask people direclty (knowing their browser history): have you ever watched porn online, they will try to come up with a lie or clever response. #2 From experience here: it was malware or someone with hardware access - you can doubt that all you want, those that cared to shared long enough in the past allways found malware. #3 in the rare cases that it was not #2 it was a bad password (123456 is not a good password) or an unencrypted backup #4 if the bounty is set high enough, people will come and try to help. Some here are even able to do so. AFAIK they usually contact the person in question in private.

you might track the hacker but to recover the coins?? impossible and also this is crypto world everything is possible here we have a bunch of pretty good hackers that only wait for a nice time to steal from you take it as a hard lesson move on with your life and protect your btc next time make an offline wallet store in on the usb and buried it under your basement things like that which you think that much more safe than put it on the blockchain or any other online storage 1.23 btc is nothing compare to klee's hundred/thousand of btc (forgive my word but that is the reality)

Bitcoin transactions are irreversible, so no, you won't get your coins back at all, unless the hacker decides to return them.

Also it would be wise to set a password on your browser all those passwords you save can just be seen and downloaded, and with malware they can download an xml sheet of your passwords saved.

Hackers can find passwords easily. In chrome, it is just "chrome://settings/passwords" (paste it in your browser tab) From there, anyone can see all of your saved passwords.
If some passwords there are the same password as the wallet.dat then that may be how the hacker stole the coins.

His computer was most likely infected with malware. If he is still using his PC, tell him to wipe everything and install a fresh OS!

As long as encrypt the file its a good idea. However if you encrypt the file there is no need for the password to be "mixed with other words". You should definitly change your practice regarding this. Security by obscurity is not 80's its 1880's [1] [1] http://en.wikipedia.org/wiki/Kerckhoffs%27_principle
