I registered here to WARN people. I installed from WordPress plugin installer and it wiped my themes directory clea. Luckily it was a work in progress. But I lost the whole site. Had to reinstall. I couldnt even get to the admin page after installing. I disabled it from the DB and then found that wordpress theme directory had been deleted.
It is a malware. lesson learnt man. never install plugins without checking reviews.
Too bad cannot rate 0
