Packed.Generic.238 removal failed

Hello, I've seen alot of posts about this little bug, and none seem to have a clear consise way of getting rid of it, so here I am with the same problem. I am running Norton Antivirus vers. 16.5.0.134. I keep getting a window that tells me I have a threat that requires attention.

The only options are get help and rescan.  If I run a full scan, Norton tells me there are no threats found.I have run Malewarebytes and it finds no threats.

 

Where do I go from here?
