Topic: New Bitcoin virus (Read 3435 times)
When ever I try to copy a bitcoin address , it automatically changes to a similar one but different
There is new information for me. I haven't yet heard anything about this before.
Maybe you put wrong address when sending.
This is a virus that we need to check and prevent while we are dealing or sending bitcoin..
The solution for this for safety like other said backup all files password and private keys before you format the whole computer.. and i think someone are remoting hs computer..
I suggest that you format your computer immediately. Backup all bitcoin wallets and passwords, destroy everything else, specially .exe files which may be infected.
Start from scratch and first time you do when you install windows should be to download comodo firewall which is a robust firewall, also download malwarebytes antimalware, malwarebytes anti ranmsonware, malwarebytes anti exploit, they do a good job for free. Remember to enable auto updates and that's about it.
Also never visit any strange websites and don't open cracked software in a computer that has bitcoin in it.

Remove everything important from the pc and format everything and install the operating system again, do not put any password now, keep your wallets out of the network
For me as experience technician for software and hardware i also recommend to back-up your important PC document files and after that you can format everything in your storage disk and don't forget to wipe out all partitions and create new drive C and D because viruses and malwares still present in drives if you don't create new drives partition. After everything is done with formatting the PC hard disk drive you must install anti virus security that is genuine and be sure to have reliable and user friendly antivirus software and then you can get back to your normal activities as wel with internet network access.
Best thing as per my opinion , reinstall OS by Formatting current Partition and remove it , make new partitions . Install good AV and Antimalware together , For example Kaspersky Total Security + Malwarebytes and always careful what you doing , what are you downloading 
; I guess no AV can protect you unless you are bit aware about your security

I, amongst the others here on this thread would like to know if this is actually a virus, of some sort. In the mean time you need to copy the wallet.dat (or export privkeys) and resync on a clean machine, move any btc from that / those addresses and then look to remedy actual problem on machine / wallet.
Am afraid if it is not a new virus, antivirus should be regularly upgraded to handle improved version of this virus. Have not had the experience of the bitcoin virus maybe it is peculiar to darknet.
With malware on your system whatever you do if your not using a hardware wallet DO NOT enter your wallet passphrase. Once opened the malware can grab the now unencrypted keys that are in system memory. Backup your wallet, ensure it is backed up, then format!
wallet.dat for bitcoin core, electrum lets you make a wallet backup unless you already have your seed.

That's why don't just click some clickbait throughout the web for there are lot of people who are taking advantage for this. I was just thinking about this virus if this is truly real and now someone got victimized. Please provide some proof and make some screenshot for it so that we can see if that is real.
Why don't you try getting your system infected with one of them ? They roam freely on the darknet,you can have all the fun you want.

this kind of virus is real, i once fell for it when I'm still new in bitcoin world, good thing for me i always double check the address before i click the send button so i didn't mistakenly sent any amount to the virus creator's address.
You can never be careful enough. It's good to have updated anti-virus on your computer or mobile and double check everything. It's very convenient to copy paste addresses but sometimes that isn't the smartest thing to do. Unfortunately new malwares are threatening every day and bitcoins are not safe from them either.
Anti-virus softwares can be easily by-passed by crypters.Read my above post.Only way to avoid the threats is to be aware of everything taking place in your presence in front of the screen.Actually all have been said here were good and effective but talking viruses on your pc now in the modern days of computer and mobile gadgets which threatens bitcoin can be prevented by most effective antivirus worldwide. Like the ones i've been using for so long time which protected my entire pc system prevents the intruder to dominate my system even hacker is firewalled by nod32 eset antivirus which have stealth ability for you entire protection.
Not new, quite old actually... Some of the more advanced variants even store huge amounts of addresses so they can match up the first few characters of the address, making it look to be the correct address, at a glance.

Oh. wow. 
I admit this is the first time I've heard there's something like this. 
Good thing I always double-triple check my addresses whenever I do transactions. I'm always too worried that I might have accidentally copied some other address or hit some extra keys.
Sometimes it's to the extent that I compare every single digit/letter.
Oh well, another thing to worry about.

This is as old as bitcoin unfortunately, there used to be dorks on HF talking about this stuff all the time. There are people who pay top dollar for this kind of coding, and unfortunately it isn't that difficult to experienced programmers. You need to be careful and verify the address every single time or you will get caught off guard by something like this. Honestly your best bet is a fresh install of your OS and practicing better security 
This and other things is the reason why I always double check the Bitcoin address whenever I do some transactions in my Bitcoin wallet. We never know what virus can already be lodging in our devices and they are just waiting for the proper time to attack, leaving us with disappointment and loss of money.
I have heard of this happening.
Maybe copy & pasting your bitcoin address is not so safe especially if you don't have somekind of security on your pc or mobile so the virus can get on it.
My suggestion would be to use those QR codes instead. You just scan the code with your webcam or your camera on your phone and you know that you are safe from this kind of thing from happening when you are copying your bitcoin address like this.

This virus is free on the black market. I think that's why it's very common to see it appear inside a file. Be careful before downloading any file. Using a good antivirus is not enough, the virus can be undetectable.
This is a very common virus and it's possible many have already fallen for it. The hacker swaps out your bitcoin address with his.
If you're using a browser to do this, wipe cache and delete extensions to see if that was the problem. If the problem still exists, then you'll have to run a malware scan like malwarebytes, and if then it still persists, you may have to do a factory reset.

This is not actually new virus because its being reported and tracked already regarding on this virus which is usually been downloaded and run silently on your computer on which anytime you copy and paste a wallet address it shows different address which have been posted by jacee above. If thats the address that you are mentioning then its really a virus.

Mind posting the address ? This is not something new,it's known virus which uses a Crypter to bypass your firewalls and anti-virus protections.As far as I know,a few Russian dudes off darknet started giving them off for free. 
Could you supply us with screenshots or something? Did you find anything malicious on your device? I'd be interested to know if this is really a virus or just you making small mistakes and being overly paranoid

This could be down to numerous things, it all depends on where you are when you are doing this, can you provide some more information.
