If it is coins you need access to and are actively using I suggest hardware wallet.  They keep the private key off of computer and sign the transaction on the device.  So it is very secure.  If used properly even if infected you are still safe with a good hardware wallet.

Other option is if you are not going to touch them at all look into paper wallet.  You can monitor the address online and send it, just keep private key on paper only.   Again it is if done properly, if not your insecure.

Those are best two options I think.

it's not hack, it's stealing let don't get confused here

bitcoin can not be directly hacked in the sense that the hacker can not steal you funds by brute forcing your public key

but he can steal those if you have an infected machine with a rootkit or whatever

The is way you should use a second PC in order to do your crypto stuff. This computer should never go to the internet. So, you can make sure that are save from keylogger, viruses and other hacking software.

well... with keylogger they can turn your life to very miserable I have to say because everything you do will be recorded, typing password to unlock wallet, generating wallet paper. The only way to prevent it is scanning your pc often and do not download potential virus software. By doing, you can be considered safe I think
so it works like a cold storage right? I think we just need a virtual machine or maybe dual boot with an clean OS (nothing got installed at all) and everything will be alright but extra precautions are advised so you might want to use a second PC like tyz said Grin

It is next to impossible that someone cracks your bitcoin wallet through brute forcing your private key. The number of keys is so astronomically big, that you are better of buying a lottery ticket.

Hacking is a whole different thing, and mostly relies on stupidity of the users. If you install dubious software or give away sensitive information, you may get hacked.

Bottom line is if you have a lot of bitcoin that you dont need instant access to then stick it on a paper wallet, if you need to use that bitcoin a lot then considor a hardware wallet, if its just a small amount then just store it on your phone or pc but be carefull with what you download. As far as i know most people arent targeted for specific bitcoin stealing programs unless the attacker knows that you use bitcoin but if you were infected by a trojan then someone would soon find you are using bitcoin.

Those hacking method are mostly brute force. You usually encrypt your wallet with a password. If your password is short (less than 8 characters ) it could be cracked by brute force methods. It needs a while, and the hacker needs a computer with lot of power, but it is possible. Especially, if the hackers knows the length and some chars of the password.
To get sure, choose a password of at least 12 characters including letters, numbers and special characters.

I keep seeing all these posts that someone can hack my wallet.  First I did not think that this could be done?  If it can be done, how can I prevent it from happening?  Does my wallet need to be online in order for them to be able to hack it or can they still hack a paper wallet?

for about 4 years since i know about bitcoin i never have my own wallet running on my pc i usually using bitcoin wallet address from an exchange or an online wallet like coinbase, after i read much information from here in this forum i have consider to install bitcoin wallet on my pc and running it as my own private wallet and i also using paper wallet that i use it for saving in bitcoin and will never redeem it untill 5 years from now, and my opinion is that wallet on our pc and paper wallet is the safest place to store our bitcoin on there rather than any other kind of wallet

It is possible that someone can just guess or brute force your private key. The chance however is so small you might as well call it impossible. Its as likely as someone winning the lottery several times in a row and will for all we know never happen as long as the sun is still burning.

Other than that it mostly depends on the way you use your machine. As AllInCrypto said if the machine that you use to control your wallet is infected by malware, its easy for the attacker to spend your coins. Its however not "easy" to infect a modern, well updated system, unless you do something to help the malware. Commonly bitcoin related malware will require you to execute it yourself, so be careful what you download and use.

Your wallet on your pc or in an exchange is only as safe as your pc  or that exchange.    Your pc could easily be compromised by any keylogger or trojan.   And as far as exchange wallets go, well, Mt. Gox is really all that needs to be said about that.     Paper wallets are safest, however not perfect because they need to be generated usually by your PC.
