Well, Ewido added this sample after 24 hours. If it is a polymorphic worm and every sample is different, then adding a definition for every sample submitted rather than developing a generic definition may not be particularly effective in preventing infection, but it is impressive that they can respond so quickly…
and another two variants EG and GM …
and You know what sux, Antivir with last database update 20.4.2006 is able detect most of them
yes Avast! not , oh well
Igor did some good work in detecting the polymorphic virus Polipos:

But at the moment both Antivir and AVG’s generic detections are managing to catch Feebs, and avast! is not doing so well.
todays 0619-2 added some Feeb variants and was able detect 3 from my list …
yet there are still 4 variants (28 different files) undetected …
avast! is now on a par with CAT-QuickHeal, F-Prot and UNA:

What happened guys? ???
Still undetected. :-[
Should I send this again? ???
Frank… you know this won’t be necessary.
I wish they take your sample in account and improve detection :-X
Well, I’ve just sent the original Feebs plus the later variant (which also remains undetected) again. I hope avast! can add them, or preferably improve its generic detection, because it seems to be way behind almost every other AV.
Well, 10 months now, and still not detected. Is this a record?
The only change is that AntiVur no longer detects this file. Weird!
Finally got a detection today for one of these files:

However, the other file is still missed.
I’ll try submitting it through the chest and see if we can better 10 months before detection this way.
Hmmm… is this an occasion to celebrate or to be worried with?
It does also make one wonder how avast! passes the VB100% test - which claims to test the ability of antivirus software to detect in-the-wild viruses - so frequently, especially when avast! failed to detect a spreading virus for as long as 10 months.
