Looks like your bitcoin database is corrupt. Have you tried again ?

What error messages did you get in your debug.log?

Im having the same error, and I;ve sent bitcoins to an adress that was generated inside Bitcoin core. This is so fcked up

It looks like that your antivirus software detects a false positive in blockchain datafile. At least Avira and Microsoft Security Essentials have done so ealier.

Can you configure your AV so that it checks only executables but not datafiles?

i fixed mine, the problem was btc core creates a 2nd folder in appdata--roaming my computer got turned off while the core was open ie corrupted files and i did an  uninstall and then deleted files in appdata--roaming bitcoin folder. then reinstalled.  
dont forget to backup your dat. file .

Just had this problem. Found windows defender labeled it as DOS/Stoned in file bitcoin\chainstate\055912.ldb while doing a bitcoin-qt.exe -reindex
Thanks for the heads up! I'll put that folder in the exceptions settings.
