So I need to have a midrange-high CPU in order to run this ? (i7-i3)? And my computer will run for about a week? (what if i turn off the computer will it continue to sync the from the end when I turned off the computer?) I have a lot to learn on this one (may be a I should build a new computer rig again and subscribe for a more stable internet connection).
By the way I did some research on the requirements of the computer in downloading BTC core :
Minimum Recommended
Disk space. 145 GB.
Download. 500 MB/day (15 GB/month)*
Upload. 5 GB/day (150 GB/month)
Memory (RAM) 1 GB.
System. Desktop. Laptop. Some ARM chipsets >1 GHz.
Operating system. Windows 7/8.x/10. Mac OS X. Linux.

And yes based from what I've heard you can have some viruses but if you will run it on windows your computer anti virus might affect the performance.
So i need to run some linux (I need to learn).
Thank you for your answer by the way. It helps.
Disk requirements are wrong there. Blockchain has increased since then. I wouldn't even bother without 200GB.
You don't need a good CPU, the most basic one that could run fine a decade ago for most common tasks would be sufficient.
It just might take a bit longer to do the initial sync. The requirements are most basic, you pretty much just need a normal PC, even an old one will do, as long as it wasn't from more the 10 years ago, I guess.
Running Windows is a whole other story that I can't help you with, as I haven't run Windows in years and never used it for Bitcoin.
You can install Ubuntu and you will see that it is nothing difficult, just a different Desktop, but using a command line would give you amazing powers that you could never have on Windows and it is very basic to use it as well.
You have plenty of tutorials on how to install Bitcoin Core on Ubuntu as well as do any other basic operations. You will not have a problem setting it up, I am sure.
You can stop Bitcoin Core at any time during an initial sync or not and it will normally continue once you turn it back on.
