1. Infected with mal ware

The files that are shared can contain viruses, spy ware and other malicious programs. A file that looks legitimate (official) could also be an incarnation of a virus pretending to be undercover. If you use P2P applications, it is likely to be difficult to ensure that the source files can be trusted. Be aware that file-sharing applications are often used by attackers (hackers) to send malicious programs. How about the sneak spy ware, viruses, Trojans, or worms into the files? Well, if you’re not careful downloading files, then the computer can be infected.

2. Privacy threats

By using the p2p applications, this means that you give access to personal information to other users. If up to financial data, personal documents, important company information, or other personal information tracked by people who are not responsible, it will be difficult to detect how many people are already accessing your privacy.

3. Hacking

There is some P2P application that asks the user to open certain ports on your firewall so that files can be transmitted. Opening a port is of course the computer allows an attacker to enter or attack computers by exploiting existing gaps in P2P applications.

4. Demand

Files that are shared through P2P applications might exist in the form of pirated software; the material was copyrighted, or pornographic. If you are not careful downloading files, then you can deal with the threat of fines or other legal action. For that, we must understand and distinguish between the public and copyright materials before doing file sharing. Take file sharing in a responsible manner.

To minimize the risk of security threats file sharing, perform the following steps:

- Enable a firewall because the firewall can block suspicious traffic before it can enter the computer.

- Update the operating system and other software on a regular basis with the latest patches.

- Install and update antivirus software regularly.

- Install anti spy ware software and update regularly.

- Never assume that by using Internet filtering, then you are protected from accessing or downloading illegal material or unwanted. Because most Internet filtering can not block P2P file sharing, it is important to equip yourself with information sharing files illegally.

- Suspect all files before the download. Scan every file before opening it. Also scan your hard drive regularly to ensure virus-free computer.
