Avast Fam please help!!

What are this log files for?i just found them at Download folder and am surprised they are about avast ,something which i was not aware of.

This are some of the logs they are just too many

Hi, they should be stored in Avast’s data folder (C:\Program Data\Avast Software\Avast\log). I don’t know why they’re at different location (location is stored in registry: HKLM\Software\Avast.… [DataFolder] value).

ok thank you …i also wonder how i got them ther
