Nyotron, provider of the industry's first OS-Centric Positive Security solution to strengthen endpoint protection, today published the results of its study of the efficacy of leading antivirus (AV) solutions against known malware, including samples that first appeared over 20 years ago, such as 2001’s infamous ILOVEYOU virus.
