I remember I tried to mine a while back. How can I check if the file(s) contains any bitcoins?

open a bitcoin wallet relating to the .dat file

You'll need to install the Bitcoin client again (if it is uninstalled). When it opens, it will read your Bitcoin "identity" (actually your private keys for spending) from that folder, and begin to update the blockchain for itself (the blockchain is a ledger of all transactions). Once the update is complete, your precise balance will be given in the program.

I think you can use electrum to import the wallet.dat file without the need to download the blockchain. Do you still have the password?

Right, there is a plethora of software that handles this. Electrum, Blockchain.info, Multibit (IIRC), definitely Armory (though it still uses bitcoind for the blockchain).

Definitely not Armory unless your wallet.dat file is older than April 2012.... (most wallet software has moved to compressed public keys except for Armory).

I installed the wallet from https://bitcoin.org/en/download, and Malwarebytes just found Trojan.Kuluoz. Any connection?

Make sure that you downloaded the wallet via HTTPS. It's fairly common that Bitcoin software gets tagged as a trojan, but I cannot answer specifically in this case as I'm not familiar with Malwarebytes or Windows.

In that binary or in the blocks in the blockchain?

Actually I downloaded and extracted the zip file, and it was inside that. I meant to choose the 64 bit exe, but my mouse is fucked up, so it double/triple clicks all over the place sometimes.

That doesnt sound right.

Mind sharing the full virus report?

This is from the scan log:

Trojan.Kuluoz, C:\$Recycle.Bin\S-1-5-21-2371484951-2026000953-552089580-1001\$RYL9B0N.zip, Quarantined, [f3008ab792ea37ff103a67f9629e1fe1]

The wallet is now up tp date with 0.00 BTC in it. Well, well...I guess that's it, then.

I suppose you checked the file signature before extracting?

Is there a mechanism within Malwarebytes to report false positives?

I don't even know what that means. Are you saying I can't blindly trust downloads from that domain?

You shouldn't blindly trust downloads from anywhere due to the attacks out there. E.g MITM etc.

You probably can trust them, but if one is dealing with money, better to be safe and verify it is real particularly given the warning. In all likelihood it is a false positive. 

If you verify the signature, that will eliminate one potential issue.

I think some antivirus give false alarms for blockchain data, rather than the bitcoin core wallet executable. What did the repeort say?

It's false positive  8)

How do you know that? It was not found in the blockchain data, but in the executable.

If signature matches it is just a false positive.

Of course.  If it is sunny, it is sunny.

But you said it was a false positive and he hasn't said the signature matched so shorena asked how you knew it was a false positive. Are you OP under a different name or did you verify it on OP's computer?

I just posted once in this thread, read better.

Didn't say you posted more than once. Responded to the thread. Read better yourself.

Good to start with reading and learning,hope to get in soon
