I think the only bitcoin wallets that are prone to hackers are online wallets. Simply using a separate computer to make a desktop wallet saves you from it. But I guess not all of us can afford to do that. What I did was I reformat my computer and installed a new OS. You can use Linux if you want so you don't have to install an antivirus. I installed ESET Nod because it's the one a lot of people are recommending. Before I even installed that, I've already made an Electrum wallet, wrote the seed on a paper, and then deleted the wallet file. Made another wallet file using the seed so I can recheck if I copied the seed correctly, and then moved the wallet file to a flash drive.
Now I'm confident that I'm not going to be hacked. The only way I'm going to be hacked is when someone found that paper which I believe no one will except me or my family.
