Please copy\paste web site adress of etherwallet that you are using for this, maybe you use some scam sites looks like myerther.
That would be my belief as well. To OP... did you use a bookmark to get to MEW? Did you manually type it in... or did you click a link in an email or on a website? I've seen a few posts about losing coin from a MEW wallet but I've yet to hear it official that it was '
hacked'.
**as a side note, if you clicked a link from a website, it'd be beneficial to post that here so others can be warned.**
