Postby chris21010 » Tue Apr 09, 2019 2:04 am

Re: windows 10 detects WU 14125 positions.xtc as trojan

Random binary data can sometimes match the signatures used by antivirus software. It is recommended that the work directory for the F@h client be excluded from scans for just this reason.

All Malware Detection software that use heuristic AV techniques can produce false-positive detections when the scan semi-random data like a large quantity of numeric data. The only dependable defense against such reports is to demand that the OS prevent those data from ever being treated as an executable program. As Joe_H suggests, configure Windows Defender to avoid scanning FAH's work files.

Please report this false-positive to Windows Defender. Note that they called it a "program" -- which it is not.
