Default ChryptoNightMiner

Hi there,

I am using Google chrome and everytime I open Facebook, get a message from Avast to say that "We've safely aborted connection as CryptoNightMiner has been detected".

I have run all Anti-virus and malware scans and it doesn't detect anything, so I don't know where this is coming from?

**It only seems to happen with Chrome**

Thanks in advance.

Have you been hacked and and have virtual currency mining software on your PC? Have you run malwarebytes?

This is a cryptocurrency miner. This thread from Bleeping Computer shows how a Chrome user dealt with one ~ she had received the same message from Avast as you have:

I think my pc is infected - Am I infected? What do I do?

This article from ESET's WeLiveSecurity site explains what happens with coin miners and mentions CryptoNight:

Monero mining malware software is quietly making a profit
Quote:
While far behind Bitcoin in market capitalization, Monero has several features that make it a very attractive cryptocurrency to be mined by malware untraceable transactions and a proof of work algorithm called CryptoNight, which favors computer or server CPUs and GPUs, in contrast to specialized mining hardware needed for Bitcoin mining.
How-To Geek shows how to deal with cryptocurrency miners and recommends a browser add-on called 'No Coin' to guard against them:

How to Block Cryptocurrency Miners in Your Web Browser

The article includes links to get this add-on for Chrome, Firefox and Opera. The Chrome extension will also install in Vivaldi.

So I think you can resolve this by uninstalling/reinstalling Chrome and then get No Coin to stop a repeat performance hopefully!

I have run Malwarebytes and it didn't find anything.

Avast scan doesn't find anything.

I have clicked on the Bleeping Computer link above, but even after registering an account, the reply with the solution is missing.

It's still happening.

Thanks.

ETA:- I have run Malware Bytes - as it wasn't that I was running before, it was Malware Hunter. So Malware Bytes found PUPs which was a program I had downloaded to try and get rid of the original issue, but nothing to do with this Cryptominer.

Even if it's all OK now, it might still be a good idea to get the No Coin add-on for Chrome:

No Coin - Block miners on the web! - Chrome Web Store

Alternatively, you could add a filter list to your ad blocker. Go to GitHub here:

GitHub - hoshsadiq/adblock-nocoin-list: Block lists to prevent JavaScript miners

Scroll down to 'NoCoin adblock list' and if you have one of the ad blockers shown there, click on the link below the list to add the filter into your adblocker.

I have it in uBlock Origin in my browsers. You could have both the filter list and the add-on I suppose!
