when i copy any address, the result always is: 1K2k7q3bHvFntdmPECWgAK3mVeb4tfNAwf
but this wallet is not mine.  ???
can you help me to fix this issue?  ::)
thank you so much.

Sounds like you picked up a bad clipboard virus.   Good thing you noticed.   I don't have any good recommendation to get rid of it, If it was my machine, I'd probably work out a path to flush and reinstall the OS.

That's virus on your computers, You must to update your antivirus to make sure your computers safe.

What do you mean? Is it something wrong with your keyboard or device? Personally it sounds like a virus to me.

What wallet are you using? I have experienced something like that they first time I used and exchange wallet. It didn't let me change my transaction address. I found out my internet server was glitching and the exchange was also having troubles. But afterwards I switched to another wallet. If you don't have any funds in this wallet, switch to a trustworthy wallet like Electrum.

Maybe, try and find tools in your wallet and click to get a new address. The wallet should generate for you a new and available Bitcoin address. You can transact Bitcoin to this address and it will end up in your wallet.

Yeah, this seems to be an virus or else this could be an issue with your computer and it's components such as the mouse and the keyboard. I believe you could  get is sought out with a complete scanning for virus or just try the same in another system. If the same problem persists there you could conclude it's the issue with the wallet and can contact the support team.

it is a trojan that is hijacking your clipboard. whenever it notices a bitcoin address in your clipboard (when you copy one for example) it changes it to the address controlled by the attacker.

the trojan is most probably the one called Trojan.Coinbitclip and you can read more about it here: https://www.symantec.com/security_response/writeup.jsp?docid=2016-020216-4204-99

Yeah right! trojan infecting your computer, Install Antivirus and Internet Security partner it with Anti-malware software and try to restart your computer then, if still in there just reformat your pc and install new OS.

Clipboard hijacking :

Trojan.Coinbitclip is the first instance of this new type of attack, discovered by Symantec on Feb 2nd. It was designed to watch for a bitcoin address copied using the clipboard, and replaces it with one of it’s own, bypassing any protection from multi-signature and hardware wallets.

There are several anti-malware software suites that can help fight malware attacks. There are also many basic security best practices to use, such as a firewall to block all incoming and outgoing connections, disabling AutoPlay, removing unnecessary services and never downloading files from untrusted sources that could prevent malware attacks.

It was discussed here too : https://bitcointalk.org/index.php?topic=1605496.0

Are you running on Windows 10? Removed malwares first by using Windows Defender. Hit the Full Scan (Not Quick or Custom). After Scanning go to History and choose "ALL DETECTED ITEMS". Remove all in the list. Much smoother compare when using an ANTI VIRUS.

After that, do some combo. Install ADW Cleaner and I think you know what to do here. Just move forward from scan to remove. Now it will restart your PC and now check if the problem still occur.

Do you have a anti-virus software, and if yes which one?
I recommend downloading and installing Malwarebytes (https://www.malwarebytes.com/). It is a very good software for scanning viruses for once, and cleanup usually.
That should work for you, and if it does not let me know and i will look into some other options as well.

sounds like a virus to me.. the question now is what do you do with a virus infected machine??
