Bitcoin-qt "Corrupted block database detected"

[boumalo]

I got the message "Corrupted block database detected. Do you want to rebuild the block database now?"

So I clickde yes and the block database was rebuilding.

When it was about 70% I updated to 0.9.1 which didn't seem to change the database rebuilding

Then when it was almost entirely rebuilt I got virus infections messages then the message "Corrupted block database detected.." again so I clicked yes and it is rebuilding again; can someone help me understand?

When the data was almost entirely rebuilt I received the same message data corrupted do you want to rebuild the database?
The coins are still on the address, I think I will just import the private keys in a better Bitcoin client; question is now : where do I find my private keys on my computer?

the correct back up file is no where to be found on my computer, I found 2 other back up files but they seem to be for other wallets, I searched for ".dat" files and "back up", I may have hide the file somewhere instead of leaving it in the default folder
