somehow the Free version installed on my PC... i did an uninstall but the uninstall was crap- it left a ton of files behind. I was able to delete everything from Avast except the file vps.etl and the directory it is in C:\ProgramData\Avast. I have tried various unlocking programs, and they all seem to be unable to delete this. How do i get rid of this unwanted, and potentially damaging file.
