Mydoom.a worm

This appears to be a brand spanking new worm, picked up today.

It comes through showing an attachment, however there is no attachment, drops itself into memory, Nod detects it upon a scan only and cannot delete. It deletes AFTER rebooting.

Cheers

Thanks for that, have seen a major slowdown on the internet today, maybe that is the cause...

 

That is a definate possibility some of these new malware put a good load on the internet when they first comeout.

 

Hello,
NOD detect it since the 1.608 update.

 

Does NOD32 detect this worm with advanced heuristics?

Yes it did with us, and now (a few hours ago) it detects it within it's virus definitions database.

Nod saved me last night from this one as well

 

Hi,
In the virus description don't appear that NOD is able to detect it using AH.

 

My best friend nailed it with the heuristics last nite. He got the definitions update about 30 min later.

 

Here are the responses speed of some AVs:

I hope that you'll understood the spanish parts.

 

Does NOD32 detect Win32/Mydoom.A and Win32/Dumaru.Y with advanced heuristics?

Answer: Only Dumaru.Y

 

I am afraid the answer Dumaru.Y is wrong. Due the nature of intentionally damaged zip archive (erong global headers, correct local headers) the worm has not been picked by AH in my opinion. Maybe you noticed, archive support has been updated on 26th.... Hope this has been fixed now....

 

This was answer of Eset support. I think that they know.
