=========================================
While P2P programs allow the creation of a network and enable you to connect with other users to upload or download
material in a fast efficient manner, (often games, music, and films), using P2P is the
cause of many infections.
File Sharing
Programs are not to be confused with the actual files one uses a P2P program to upload/download.
None of the files you download can be guaranteed to contain the content as described by their name. Indeed many can and do contain
viruses, trojans or spyware; especially as file downloads are typically from unknown sources. Malware writers can use methods to circumvent security programs.
If you have downloaded
cracks-warez-keygenerators, the odds are you already have an infected computer.
Many entertainment files infringe the
copyright laws and if you share them, knowingly or unknowingly, you are putting yourself at risk of prosecution and huge fines.
