While doing sync on my wallet, my AV detected virus in the blockchain

[0x54444e]

So, just installed my wallet a week or so ago, and around "1 year and 17 weeks behind" my AV ( Bitdefender 2015 ) detected an virus inside the chainstate, how is that possible?

what is "your wallet" ... ? 

Bitcoin Core (desktop)

From the bitcoin official site on the download section, last version.

OK, so ... create exception in your AV for the folder of bitcoin core.
AV are bad because they use somes counter fighting strategies (and they fail ... usually).

It is a false positive, a signature in the blockchain matches the signature in the virus database. Just whitelist the folder and continue, the 'virus' cannot do anything to harm your computer.

Since the blockchain is a variation on the infinite monkeys/typewriters theme, in that shit in it is so well encrypted it's kinda random, every virus signature will eventually be in it.

Sounds like a retarded viruskiller, as the blockchain data is just data, it's never being executed.There can be anything in there, it just doesn't matter.

[Sempruls]

no problem at all
just make exception for your bitcoin-core folder blockchain

[pozmu]

That's normal, people are storing a lot of different types of data in the blockchain, including viruses.
I don't think making blockchain folder an exception is very good idea from the security point of view, some malware can make use of that... Better use AV software that takes care of this issue without having to create an exception.

[SargeR33]

As other suggest, make an exception in your AV. I had the same issue, after some research it seems back in the day there were viruses designed to run scripts on your PC to mine for somebody else. These signatures probably pick up on something like that or something that isn't even remotely related.

I would be cautious though, I'd use another AV and do a scan just to be sure.

Report the false positive to Bitdefender.

False, there is nothing encrypted in the blockchain. All transaction data is directly readable.

This.  It is a false positive.

Yah, I wasn't terribly clear that I meant that there are some products of encryption in it, like block hashes. Anyway, lots of essentially randomish strings.

This is a false positive caused by many anti virus and many treat it as a virus or malware due to how it works. Simple solution to that white list it in your anti virus and should be fine. But I would also look it up to be on the safe side or back up all wallets and delete it all and start fresh and import your old wallets first. Then id do a scan of full system to make sure their is nothing on system that might cause a threat to your coin.
