I've also been exposed to malware viruses on my laptop where you try copying your bitcoin address, but actually when I paste it precisely someone else's address that appear lol. If you're not a keen and unfocused person, hacking this method can be very detrimental to you, make sure you update your anti Virus...
That is a very old virus and yet it still creates problems for the people and one big problem is that many people do not take the extra seconds to verify that everything is OK before sending a transaction and this means they will lose their money to those hackers, so if people like that are unable to take the needed precautions to protect their coins then it may be a good idea they get a hardware wallet that way those problems will be a thing of the past for them.
I say this because securing your computer is not a small feat especially if you are using a operative system full of bugs and backdoors like Windows so your time and money will be better spent in doing something else and just getting a hardware wallet.
