Hi enddays,
This is what MS say about this:
Technical Information (Analysis)
VirTool:Win32/Obfuscator are detections for programs that have had their purpose obfuscated to hinder analysis or detection by anti-virus scanners. They commonly employ a combination of methods including encryption, compression, anti-debugging and anti-emulation techniques.
These obfuscation techniques are used on various kinds of malware. The malware that lies "underneath" may have virtually any purpose.
So the find can also be an obfuscated False Positive or a program that used these techniques to prevent it could be resource engineered or resource hacked.
If you still have the flagged file update to virustotals and see what av scanners flag it as real malware,
or upload it for analysis to wepawet.cs.ucsb.edu where you can see de-obfuscation and analysis to see if it is suspicious, malcode or false positive,
If genuine malcode upload to avast for analysis and adding for their signature base,
