Yes that is a fault positive. I have not had any reports of virus issues before (at least none that I remember). There are many people using Paste As File including TechZilla with no issues.
Here is are scan results from VirusTotal.com - https://www.virustotal.com/en/file/1d8c63031e669594bfc3051f80fe2dd69557b8eb5c1880ce875ec712039fa413/analysis/1425500344/
