There are quite a few Linux / UNIX exploits and rootkits out there, it would be nice if Dr.Web searched for these.

Examples:

http://seclists.org/fulldisclosure/2010/Sep/268 ( the recent 64-bit/32 linux kernel exploit ) (tested, not picked up by Dr. Web)

http://www.rootkit.nl/projects/rootkit_hunter.html ( root kit detection )

http://www.chkrootkit.org/ ( root kit detection )


If these features were introduced I would definitely buy a license.

Thanks!

Did you test a page http://seclists.org/fulldisclosure/2010/Sep/268 or a compiled exploit?

I compiled the C on a 32-bit machine via gcc and moved it over to a 64-bit system.

Neither the C sources nor the binary were picked up.

Do you know, what on another PC with another compiler you'll get another binary file?

I compiled it on another 32-bit system at work and Dr.Web didn't pick it up either. I tried scanning the 32-bit compiled binary on a 32 and 64 bit dr.web install without success (well, without detection)

You should obtain actual virus definition bases first.

Run update.pl? Sorry, I don't know what kind of Dr.Web product you use. I can only see old virus finding engine and very old (near March 15) bases.
