ESET, the leader in proactive PC threat protection,  announced the availability of a new, powerful online scanning service. Powered by award-winning ESET NOD32 Antivirus software, the ESET Online Scanner is a free Web-based service that allows users to scan and disinfect systems, hard disks, compressed files and email -- without uninstalling their existing antivirus solution. With the ESET Online Scanner, non-ESET users can identify hidden threats, get a "second opinion" on the health status of their computers, and determine the strength of their current malware solution.
