Netadaptercx.sys |link| Review

If you find this file located in a different directory (such as C:\Windows\Temp or a user profile folder), or if the file lacks a valid digital signature from Microsoft, it could be a piece of malware masquerading as a system file. In such cases, a full system scan is mandatory. However, for the vast majority of users encountering errors, the file is legitimate but malfunctioning.
