I received a notice saying that my internet connection was used to distribute infringing material but I didn’t know I was uploading copyrighted files.
You or others who uses your computer may have installed Peer-to-Peer (P2P) software on your computer. When files are placed in the shared folder of the P2P software, they are available for other users to download from your computer. Unless the copyright owner has authorized you to distribute those files, each time someone downloads a copyrighted file from your shared folder, your internet account is being used to illegally distribute those files. To prevent future file uploads from your computer from happening you should either remove the P2P software from your computer and/or delete any files from the shared folder that you are not allowed to share with others.
