avast! antivirus is probably the most visually pleasing anitvirus application out there. Even though the default icon is decent I felt compelled to make some custom hi-res icons for it
There are 4 box icons (all identical with the exception of the label), and a group box icon for a total of 5 icons.
EDIT: I have renamed it to a more accurate title (avast! Antivirus Suite), and added a Suite icon to the pack.
I can't take full credit for this because the original images are from avast! and all I did was make icons out of them. So the real credit goes out to the original designer who created them for Alwil Software.
