Norton Security has stopped all GPUGRID tasks on my Windows computer, because it detected the following file: SONAR.am.Clg17.
It is listed as:
Risk Level 1: Very Low
Discovered: November 3, 2016
Updated: November 3, 2016 10:58:44 PM
Type: Trojan, Virus
Infection Length: Varies

SONAR.AM.C!g17 is a heuristic detection designed to detect malware, adware, and potentially unwanted applications based on suspicious behaviors uncovered from cloud data.

Anybody else had the same problem?

I had exactly the same problem and I have opened a trend in the Server and Website (Sorry, I haven't realized that this trend was opened already).

I copy my post here (Please, can the administrator close the other trend ?):

My antivirus shows one alert that says acemd-918-80 in the folder of GPUGRID is behaving suspiciously in my computer and detect the threat SONAR.AM.C!g17.

Is there anyone who can tell me if is a real threat and I must erase this archive?

If I scan directly the archive the antivirus don't detect any threat. What do you advise: erase or continue with acemd-918-80 ?

Is acemd-918-80 necessary for crunching?
My SO is Windows 10 64 bits.

Thanks in advance for your advise.

I stopped the task in process(0,39% done) and when I tried to continue I got an Error (error de computació- computational error). That help in the decision ?

The app hasn't changed since last April (acemd is the main application executable, it is definitely necessary).

For some peace of mind, I can suggest to try and submit it to www.virustotal.com .

The "heuristics" seem rather obscure. Even the well-known Atom editor triggered a false positive: https://github.com/atom/atom/issues/13234
