How to remove OSX.Trojan.Gen

System scan with Avast indicated three infections. The infections were located in /Users/my name/Library/Caches/com.apple.Safari/WebKitCache/Version 11. The files were described by Avast as “JS:ScriptIP-inf [Trj]. I removed these files using Avast.

Additionally, a program called Task Explorer (which scans with Virus Total) indicated the presence of a OSX.Trojan.Gen file located in /Users/my name/Library/Application Support/Helper/Amerisoft Helper Compact.app/Contents/MacOS/Amerisoft Helper Comoact.

Amerisoft Helper Compact was not flagged as an infection by Avast, however.

Does anyone know exactly what this Aimersoft Helper Compact Trojan does in Mac OS?

If this is malicious, how should I remove the file?

I am using Mac OS High Sierra Version 10.13.4 on a late 2013 iMac. Any advice would be much appreciated!
