Hello,

Since two weeks I'm into this new world of crypto currency and bitcoin and well I want to buy my first millibitcoin in order to see how all this works !

But before I do this I need to download a wallet and before I download my wallet I need to be sure my computer is clean, obviously.

How are you sure your computer is clean?
My anti-malware is the basic windows defender.And of course I have CCleaner.
