???
If I remember correctly (you can search the board for the 42100 keyword) you shouldn’t worry that much about this error.
But I’m not fully sure…
Welcome to forums 8)
Charley… the link (of any avast forum search) gives you nothing 
Only the own user could see the results 
Sorry … I was not thinking about that. :-[
I just redid the boot scan with NO 42100 errors
Only two things different
I’m guessing the latter did the trick. I had installed Visual Studio since the last auto VRDB and Visual creates piles of files all over the place, which would therefore not have been included in the VRDB yet. I was doing the scan before doing a cloning of my system disk because of the major changes. I expect this to be the norm not the exception. I think error 42100 does not qualify as a “feature”.
?Any dissent? I’d be real curious to hear. All the many, many times this question has come up, this answer hasn’t been offered.
