Dyna:BitCoinMiner-CR [PUP]||mul is the name given to the threat.

When I attempt to open it from the shortcut, it says "Error Opening Block Database. Do I want to abort?"

Now I need to know what is going on here and what my options are.

This has been used as a hot wallet, so it doesn't have a high balance. But, I would really like to recover it, if possible.

Any help is greatly appreciated!

Edit: I have been reading other threads about antivirus software flagging Core as a false positive. I am not seriously techie; so, I may need some guidance as to how to determine if there is a true threat.

What should I do first?

I don't know what kind of antivirus you are using, but I am using Avira and I open up Avira from the task bar, press F8 to enter the configuration and find where it is located the bitcoin core wallet folder and I add it as an exception to the database. I do so with almost every mining software.

No matter what antivirus you are using, you should find the folder where bitcoin core is located and add an exception to your antivirus. Another thing to be done is to go the quarantined files and click restore from there. These are a few options to try.

I use AVG Internet Security.

I just ran a full scan using AVG and it has now identified two more files that are associated with the Ethereum wallet that I attempted to sync a month ago. I was not happy with the Ethereum wallet and decided to not send any ether there, as it was very slow. Does the Ethereum wallet also cause the antivirus to generate false positives?

The notable thing is the dates shown on all 3 files are Mar 5, May 21 and 23. Why would AVG just now be flagging these files?

My questions now are -
1) How likely is it that these are false positives?
2) If I now uninstall the Ethereum wallet, shouldn't those files also go away?
3) If I want to get more comfortable that this Core wallet file is not malicious, what are some things I could do to make sure?

The 2 Ethereum files that have been quarantined are -

C:\Users\L**t\AppData\Roaming\Ethereum\geth\chaindata\018709.ldb

C:\Users\L**t\AppData\Roaming\Ethereum\geth\chaindata\118445.ldb

I cannot do an uninstall on the Ethereum wallet because it does not appear in the Programs Control Panel, which is something you all understand way better than I do.

Is it better to allow AVG to delete these 2 offending files or attempt to delete all the files Ethereum installed during my failed attempt to sync?

Its a false positive, because there are sometimes miners in virusses.
Its safe to whitelist the bitcoin core wallet and its files.

Don't delete or uninstall them mate, download only from Ethereum.org and Bitcoin.org any wallet you are trying to install always download

From a trusted source. but now you already installed them and suddenly anti virus is showing you alerts? well you past the important part

Already mate, restore them and continue as before.

Install source was good. Wallet had been syncing properly for months and transactions working.

In using AVG, I have learned that they are over zealous in their identification of threats and will quarantine things that are not infected and are essential for health of the computer. So, they can really screw things up.

Furthermore, when I go to restore the falsely quarantined file, I get the message "You are trying to restore a file from the Quarantine. The file already exists. Should the program overwrite the existing file?"

Do I want to overwrite or not? My guess is no; but, I'm not sure what I will get.

I swear! Someone needs to come up with an Ulcercoin!

This is the 2nd noobie freakout in 2 days. I need a break! And Ive been doing these crazy coins since 2013!!

Oh yes, I restored and overwrote the wallet file and it's fine. Will definitely whitelist with AVG, so they don't mess with my wallet(s) again. Should do it for all of them.

What should I do first?



1. Backup the wallet

2. Uninstall the anti-virus software


Anti-virus is a scam really. Either your OS is secure, or it's not. Anti-virus makes no difference to computer security.

What you should've done are :
1. Open virus chest and select "Restore and add to exception" for all bitcoin core files (whether it's wallet file, application or other files located on bitcoin core directory)
2. Add bitcoin core directory to avast's scan exception
3. If your wallet files isn't exist on virus chest anymore, restore from your backup (assuming you backup your wallet files).
   If your wallet files isn't exist on virus chest anymore and you didn't perform any backup, you could try recover your wallet files by using recovery software such as Recuva

Also, please do not necropost / bump old thread and make a new thread instead.

Hm, maybe you should check avast pro antivirus review to find whats wrong with your antivirus. I think that the main problem is in authenticity of your antivirus. You shouldn`t download from foreign resources only because this version is for free. If you would buy the original one you will lose your headache for a long time.

*sigh*

It's like this

When you're using Windows, the computer tell you what to do half the time, often the half where what you want is actually something that helps you

Anti virus is another layer of Windows telling you what to do, in essence. Windows is not and never has been secure on it's own, anti-virus doesn't fix it, it just makes the machine so difficult to use that viruses can't do their job. But then neither can you; everything's slower, and the AV is always stopping you from doing something that isn't even unsafe.
