I’m not a computer expert, not even close to a security expert, but just understand that your a target. If you are on this forum you probably have precious SAFEcoins, these can be stolen if you download and install something on your computer or even click on a link.
An attacker could just put something on the SAFE Network even and let you go and play there.
The computer that you do your silly things on (download software & click links) needs to be a completely different one from the one you use to do your financial business.
Always have 2FA activated if you don’t have a second computer. This is not an attack on anyone, it’s just to warn you ants to stay alert, we’re in this for the fun of it, but… 
Poof your SAFEcoin could be gone
You have been warned!
