(SORRY BAD INGLISH)
It appears to be a worm, http://www.systemlookup.com/search.php?type=filename&client=malwaresearch-ff&search=netreg.exe and http://www.bleepingcomputer.com/startups/netreg.exe-7377.html.
Try a search for its location, if you can find it, send the sample to avast for analysis.
Send the sample to virus (at) avast (dot) com zipped and password protected with the password in email body, a link to this topic might help and undetected malware in the subject.
Or
Send the sample/s to avast as a Undetected Malware:
Open the chest and right click in the Chest and select Add, navigate to where you have the sample and add it to the chest (see image). Once in the chest, right click on the file and select ‘Submit to virus lab…’ complete the form and submit, the file will be uploaded during the next update.
If you haven’t already got this software (freeware), download, install, update and run it and report the findings (it should product a log file).
