Looking forward to beta testing next year.
Why don't you enjoy the forum until there?
There are a lot of experience and knowledge to share, not just on avast, but in all security and applications fields.

I will.
I have an interest in Avast as a user and it's my recommendation to family and friends that need a quality free antivirus.
Glad to help where I can.

tuareg: 62,5%
insane: 100%  :)
the rest of the ones from clementi's set is currently unchanged.
A little bit less technical and more people could start to imagine what are you talking about ::)

i was talking about the improved poly detection; the detection of the 2 mentioned viruses is now respectivly higher than 4 weeks ago.

Still not good enough. I expect no less than at least 50% coverage (100% detection that is) of mentioned samples (this means at least 6 samples being 100% detected). Still good to see some progress... 100% would be even better.

Agreed. 8) 8)
I have found the folks here always ready to help.
I have not been concerned by the poor showing on the polymorphic tests. Maybe ignorance is bliss.

ook.. Insane/Devir looks good... and about Tuareg/Driller - good to know the score, we must prepare more samples of this family and improve the detection.. thx to Andreas for a quick re-test of his poly set ;)..

new poly module is included in VPS since august 13. and 25 detections were added till now.. a little progress is visible in "hardcore" polymorph table, but Andreas has many polymorphs in his set (Twinny, Legacy, Zaprom, Orez, KME.........) and we must detect them too, no matter if they are "visible" to ppl... so, the results of re-scan aren't bad, when you assign them to the ~2 weeks block starting from august 13...

true. avast already shows a big improvement after 4 weeks when scanning the set of missed samples.

Thanks IBK for the explanations.
Glad to see that avast policy is in the right direction.

IBK is any chance for tests to include support of unpackers like various install packers etc. ?
but i guess that's way too complicated and time eating

I don't think it's a good idea... It doesn't really matter whether an antivirus unpacks the packed archive (and detects the malware inside), or if it detects the malware from "ouside", using a signature taken from the packed installer itself.

So yes, it is nice to be able to unpack various archives, but "more unpacking" doesn't necessarily mean "more detection" (as many readers would probably assume, so the test might be rather misleading).

I was wondering... Hmmm... Maybe I am Wrong...

But more unpackers means less signatures to detect a malware?

Lets say that malware x, has been packed with ten diferent packers creating ten different files (versions of malware)...If Avast has the 10 unpackers, it will only need 1 signature to detect them all. The unpackers will extract the malware from the pack, and the signature will detect it inside.

In the other way, if avast doesnt have some of the unpackers for some of the files that were packed, it will have to create another signature to detect each sample that doesnt have the related unpacker in avast, even the malware being the same, just packed with a different packer.

What I see is that with more packers, the pro active protection increase, as it will not be necessary to receive another update with a new signature of a know malware that was only packed with some other packer...

Am I right? This make sense?

Thanks for your time,

Elminster

The question is - how many (existing) variants of malware are just repacks of other, already detected, malware. If most malicious files are "new" - it probably won't be detected, no matter if it's unpacked or packed with any number of packers.
I can't say what's the reality - probably somewhere in between.
