There are things called 'clipper' viruses, that when you paste a Bitcoin address, a foreign BTC address will get pasted instead of your own, and funds might get transferred to them instead of you. If your PC is clean without any viruses, there should be no problem, but I like to take note of the first and last few digits of the address to make sure that they are the same.
Op, you shouldn't forget this one. Always triple check if it is the right address you have pasted. About the quote above it is called clipboard hijacking where it replaces every wallet address you copied and pasted the wallet address of the person who able to infect you with such program. ALWAYS TRIPLE CHECK EVERYTHING.
