lol im so paranoid i even bought 4 usb sticks to put my wallets on it,
is it a problem if the wallet.dat has been connected to the internet before? or just get the wallet.dat offline and you're fine?
edit: btw thx 24, deleted teamviewer right away lol
Theoretically speaking as soon as the wallet touches an internet connectecd PC it becomes at risk.
Problem is that i only have 1 pc.
And i don't mine coins so i don't see the point of keeping a wallet on a pc thats conected to the internet.
If you dont have a second PC to generate an offline wallet then you can use Virtualbox to create a 'virtual PC'. Just yank your network cable out or turn off your router and install windows on your virtual PC (Called a Virtual Machine or VM). You can then generate a wallet that way. Using a Virtual Machine is also a good way to test any suspicious software before installing it on your actual PC.
If you are going to use a paper wallet you need to understand how change addresses work or you may risk loosing coins when you transfer them back into a wallet. Heres a reddit post that explains it.
http://www.reddit.com/r/Bitcoin/comments/1c9xr7/psa_using_paper_wallets_understanding_change/Behind every address is a "Private Key" which looks similar to a standard address but is longer and this is what you are really backing up and trying to keep secure. As long as you have your private key somewhere (be it in the form of a wallet.dat file or a paper wallet or simply just writing the private key down on some paper) you will ALWAYS be able to get your funds. Every wallet ever created now and in the future (some online wallets wont allow you to import private keys) will accept your private keys and you will get access to your funds.
If an attacker gets your private key he has access to all your funds even if your wallet.dat is encrypted.
