Help! windows\system32\svchost.exe Malware

My last computer was crashed from this very same Malware.  I got it from one website specifically and now it is STILL following me.

I bought a brand new computer and installed Norton (thank God for Norton)!   I noticed that in the Norton history it keeps Blocking Unauthorized Access with a Medium Severity and logged it as a Open File.  (the actor is always the same - windows\system32\svchost.exe)

This thing is ALWAYS trying to get at my computer.  I get at least a dozen history reports throughout the day of it trying.  How in the world can I get rid of it once and for all????

I called Norton and had a tech go through my computer... they didn't find 'it' and just noted that it was a good thing Norton is preventing it access.  I looked under the Windows system folder and couldn't find svchost.exe anywhere.  I just want to delete it off my computer....

 

Where is it?
