Sudden influx of threat notices

I'm using NIS retail 2014 on a Windows 7 machine. After booting up this AM, I have been receiving alert notices continually concerning 3 possible threats: skype.exe_-35574313755191061; jxpiinstall.exe_6355.......; and namebench_1.31.Windows.exe.... NIS shows that the threats have been blocked or removed. However, NIS continues to continually report the same threats over and over. Are these real threats?? If so, is there a way to remove them? This is my first post, so I'm not certain this is the proper venue for addressing the issue. Would appreciate guidance. Thanks.
