-I saved these details for two days on my desktop since I was out of ink. Is this dangerous? I use Windows Defender...
No, it's not dangerous as long as you don't run unknown executables and don't click on unknown links.
Tell you what - take a picture of yourself naked and put it on your desktop.
You'll be more motivated to secure that picture from going public, and your coins will be safer too.

Yeah, as simple as that. Do not download files that you don't understand, do not just click next and next when you install a software. You must read the whole setup, because sometimes there are malwares there. I never use antivirus, but my money is fine. That because I only use my computer for my job only. I only use it for work, and watch movies, that's it.
