Everyone has viruses, but why would this one appear after hours of inactiviy.  Very reluctant o unqqurantine due to long random filename, bad eyes, and my zero knowledge of what directory is,  Hence can not submit  REALLY need way to submit from quaranyine or restore to new location.  Any ideas.  Anyone else see.  For now will ignore.
