Yeah I guess it's not really a cold storage then, I created it with wi-Fi on and it was connected to the Internet for a few days. But that first one is now deleted. Maybe I can create another one completely off-line and transfer the coins

If you're confident your computer is safe then I might not be an issue. The question is how confident are you that the computer wasn't infected before creating your wallet? I've had a hot wallet on my main PC for years, and haven't had any issues. But I'm extremely careful, and even more paranoid.

If you want a truly "cold" wallet, then the best approach is to take every precaution you can. My favorite method is to use a machine with a newly installed, open-source OS (Ubuntu.) Once the OS is set up the way I like it I will install Electrum, but before I create or restore a wallet I will disable all the networking hardware and USB ports in the bios, then lock the bios with a password. Once I'm confident the machine is secure, only then will I restore or create a wallet. The machine will never get connected to internet or any other computer again unless it gets purged first. If I need to sign a transaction it will be transferred between my online machine and the off-line machine using cameras and QR codes.
