BITCOIN VIRUS!! BUG!! HACK! WORM!! : STEEMITIANS YOU ARE BEEN WARNED~!! [IN SMALL LETTERS]

Hello Everyone~!
Well ,I'll make it short and quick because its important.
well,yesterday as I was just transferring some amount to a bitcoin address,normally a person would simply copy the address and paste it where it is required....and i did the same but i realised something that it was different from the address i copied so i just checked(....which i hardly do)...and i was shocked it was different!!..so i copied it again and pasted it ....again the address pasted was same as before but was not the one which i copied!!
i was horrified!...a virus is there~!!...so i did multiple checks and copied and pasted several times with different addresses and data on a text editor.here are my findings :
1.if you copy a bitcoin address and paste it ,it always changes to a specific unique bitcoin address always.for example, i copied my bca(bitcoin address ) ie 34zaebtllpbfwtc7ayrwvseexuzfgmk2kg ad pasted it ,it always changed to 13aqmiworwr6grdfzswq1tdxdn9qkhwapd(even now it happened ..i copied my bca and pasted it ,it automatically changed)
2.well ,hopefully this didn't happen with my litecoin address.so its safe to say(for now) the virus is only their for bitcoin,but there might be new viruses with might attack other cryptocurrencies.
3.algorithm of the virus is simple :
it simply changes a potential bca into its own bca.
see if you copied one or two letters(numbers) less from your bca and then paste it ,it doesn't change.~!

1. it have only received and never spent bitcoin.
   well,that could be possible with any normal person too, but the amount he's having right now is about 9 btc...which is a big amount~!!
   here's its address summary :
   https://blockchain.info/address/13aqmiworwr6grdfzswq1tdxdn9qkhwapd?sort=0
   
   5.well its very dangerous and he's stealing your coins!
2. i don't know if it's only for windows or not.
   what you can do :
   1.keep a check on bca you are coping and pasting.
   2.check your computer for viruses.
   3.be alert,its your money after all.
   4.if its on your system too,then to copy and paste addresses simple copy 1 or 2 letter(numbers) less and add them later thats what i am doing.
   5.i don't know how to remove the virus,if you know help me~!

thank you for reading this post~!
