Then what do other AV programs do?
Well, I would like to know... I still somehow doubt they can delete it.
Recently, we talked with Vlk about a special way to do that, but came to a conclusion that it's too dangerous (other files may get corrupted).
Vlk and Igor, please, do not give up... What's related by Erik is, in my opinion, a think that annoy or panic the users... Maybe the other av just do not say anything and delete the file on next boot
Probably not but, how to correct this in avast, even eicar.com files are not 'deleted' and give error, specially the temp files.
