AntiVirus alert: NetFilter malware in NetWorx. False alarm?

There are a few virus, trojan and malware alerts in VirusTotal. Check this report:

I was astonished to see NetWorx as a riskware. Is it a false alarm? What shall I do?

This kind of alerts have nothing to do with viruses.
NetWorx uses a driver called NetFilter for filtering out local traffic. Unfortunately, this driver was also misused by others in some malware, that's why virus scanners are showing the warnings. If you are still concerned about these warnings, you can use the portable edition of NetWorx which doesn't include the driver, or simply choose not to install the driver when you are installing NetWorx.

NetWorx is perfectly safe, just make sure you ALWAYS download it from SoftPerfect.com website
