It is possible for the host machine to infect the virtual machine, its harder the other way round. Anyways, it is possible for the malware to record the screen and get your 12 word seed. Use one of your pendrives to run a live copy of Tails and you will be fine.

You can do whatever you want with the VM and the pendrive, just remember the 12 word seed. It is the most important thing in the Electrum cold storage. Pen drives can be prone to failure so I don't really recommend using them.

So just download Tails and do exactly the same thing just with cold wallet(no internet) on Tails and watch-only on a PC that's online.
Then store the wallet file on pen drives and remember + save the 12 word seed on a piece of paper in case of emergency.

That's gonna work and will be safe, right? Also, just wondering if the 12 word seed is the only thing that is required to get into a wallet, then isn't that not so safe?
There has to be at least 50-100 milion of people using etherum so it shouldn't be so hard to get into at least 1 wallet with random 10-20 combinations you write, no?

Yup,, just boot tails as a LiveCD. The 12 words seed is all you need to get into your wallet.

You're not the only one that thinks that way so I'll break it down for you, its quite simple. For a 12 word seed, there are 2049 possible english words. With the English words, there are 2049^12 possible combination of seeds. Assuming I can bruteforce seeds at 1 million seeds per second, I can run through 3.1536x10^13 seeds per year. I'll be able to run through the possible seeds in 1.7365884x10^26 years. In comparison, we have 7.5 x 10^18 grains of sand on earth.

Thanks a lot for your replies mate, really appreciate it!
Last question if you're still around, can Tails get infected by main OS in any way? I always keep my PC clean and have antivirus enabled all the time. I'm almost certain that my PC is not infected, but it's better to assume otherwise.

Therefore i'm not sure if i can just run it on pendrive and boot it on my PC that already has Windows 10 installed, then just choose for it to boot from pendrive.
