Tips on how to prevent the attacks of hackers.

Check with the project before you download a wallet or other software sometimes with virus. (What are the 3 types of Malwares?)
1.Virus. A computer virus can automatically create and install a copy of itself on a computer's files, and – like a virus in humans – it can spread from computer to computer
2. Worm. Much like viruses, worms can automatically replicate and infect multiple files
3.Trojan
