My account has been hacked

I have an account with myetherwallet I just checked my account just a few days previously, there was 0.197+ etheruem in my wallet. But when I checked on it again just today it just says that I have 0. I just found out that someone has successfully got access to my account and just withdrew it all to his account.

After this event I don't know whether is it myetherwallet is just not safe or my computer just got a virus...

But what I see by tracing the transaction to whom it was paid to, that person had 4 other accounts withdrawn to 0 just like mine, the owner of that account then afterwards immediately changed his acquired etheruem into altcoins I presume, cause his account doesn't have much etheruem left and there was also a withdrawal of 5 eth, to another wallet, 0xa1a1d868e1A905f6785ac1E8D54d2B97DB24e2D7 and laundered again to 0xfb9F7F41319157ac5C5dccaE308A63a4337ad5d9. This is likely it is that person's personal wallet cause it has 200+ eth. I can also tell that this person like to gamble due to some betting tokens that person owns.

Not only that, he is hacking people every 10 minutes, you can see for yourself, the accounts that sends him money are the same as the account that my account sent to the first account, so be careful if you are holding etheruem now

Lastly what I can deduce is that he also uses kraken a lot, most likely the person uses it to convert his ill gotten token into cash.

this is my account being robbed clean

this is the his account with some other unlucky victims

this is the laundering, new account that person just made

Finally, his ultimate nest.

This must be really my worst day.
