Eset NOD32 and Online Scanner
Eset provides a free online scanner and a 30-day trial of their NOD32 antivirus program. Both malware scanner services by Eset can detect worms, rootkits, adware, spyware, viruses, trojans and other types of malware.
Eset NOD32 Scanner - This antivirus scans not only the computer but can also scans and protects emails, documents and websites against malware. The only item to note when using the NOD32 antivirus scanner is the default setting for Potentially Unwanted Programs (PUPs) scan. The real-time and on-demand scanner for PUPs is disabled by default. It's important for home users to enable the on-access and on-demand scanner for PUPs. Office or enterprise users can opt-out of enabling PUPs detection if their IT administrators need to use such program for logging purpose.
The antivirus scanner by Eset performs well especially if you are using the default setting with smart optimization enabled. Disabling this feature in Eset scanner will not use the highest scanning speed and will scan all items that the user has selected in the ThreatSense core setting. ThreatSense is the proactive detection technology used in Eset products with options for customers to adjust the file types, file extensions and level of scanning to be used by the antivirus program. Keeping Smart optimization enabled will use the setting set by the Eset development team. Note that this feature is often updated by their team via regular updates.
The free scan using the NOD32 antivirus program is available for 30-day trial only. After 30 days, the program will no longer receive product and virus detection updates. Users should remove the software if you do not plan to subscribe to the Eset service.
ESET online scanner - Like other online free scan services, Eset online scanner checks the system for malware for free, but does not provide real-time protection. The online scan includes anti-rootkit detection, quarantine options and allows removal of detected threats for free, as well.
