Not sure what this is or how to fix it but I believe this has to do with AVG, which I removed, because AVG is apparently gunk now.

I also note there's one last registry bit for AVG, avgdiag? If I delete it will this junk go away? How do I fix this since I already bloody well got rid of AVG. This error is in the list every few days I note. Any help would be appreciated.
