I have a strange problem, When ever i copy the bitcoin address and paste it any where online or in any documents it changing to the another address. could any body know the solution how to fix this problem. I already scanned with the malware bytes but no use.

Sounds like clipboard hijacking. I haven't experienced one myself but I've read that they're mostly comes from some malicious site ads. You should install an antivirus and have it check your PC

there is a form of keylogger on your computer that is changing what is inside your clipboard. try using a rescue disk, a live CD with antivirus, malware removal tools in it and boot up your system with that to check your system and remove malicious programs.

It sounds like more then a problem, sounds like some sort of security issue.  It is NOT normal or ok for BTC address to change when being pasted.  This sounds like you have been compromised.   It might not have found it but if this is something you can replicate it sounds like virus/malware.  Does it always past same address?  If so what is it?

I would get all hot wallets off that machine if you have any.  Also if you had any private key's stored on it send coins to new safe address.  Don't sign into anything important, and if you have change password and not use it on that computer till you can find out what is happening.

maybe some add-on or extension in your browser from a bogus company?

I think you can also try to re-install your current operative system...

Its always pasting the same BTC address
BTC address : 1JZ1rwRwyzc2LhD6SfEiKnrd2KPysMqx7w

this address has never been used so it is not possible to tell anything about it.
do you have an antivirus on your system? you might want to restart your system and boot into safe mode and install antivirus and scan your system.

also regarding my previous comment here are two links for you that can help you for removing malware,... if the normal way of installation and scanning inside windows didn't help:

I think your pc is infected of malware. Many of my friends also have that problem and they said that it because of the program that they downloaded online. So for me it's better to have a full scan by your antivirus software and also scan by using malwarebytes because i think it's one of the best to find and clear those malware on your computer. Just my suggestion :).

Changing an address when copied is extremely easy to do. Run an anti-virus scan and be sure to check all your webbrowser extension. Remove all that you don't know / trust and reinstall the rest as well.
