Win32:Sobig-F vs AVAST4

Viruses and worms
1

today somebody sends to me via email this virus

i use avast4 pro(with a free serial-i was a beta tester)
and outlook 2000(not express)

ok
the resident shield detected it
but the on-demand scan with full setting DOESn’t detect!!!

so i re-open outlook 2000 and i used the residend shield to delete it

why the on-demand scanner doens’t detect?
is because it was in the outlook database…?

2

What were you scanning with the on-demand scanner?

3

scan all file by content
sensibility test whole file & ignore …
packers all

but i think there is a bug, in a system with a lof of ram, the unpacker engine doesn’t work

4

If I remember correctly, Outlook stores its messages in some kind of compressed file; these files are not handled by avast! unpacking engine, so there’s no wonder it was not found.
