NOW, if you also make sure that the Heuristic feature is selected for the respective On line Access Protection modules, and you have a nice secure setup.
I see heuristics only in Internet mail provider ( I don't use Outlook and I turned off p2p provider). Was that what you mean?

Thank you for taking the time to share your test results with us.

On the subject of false detection in cpav.exe again...

Quote
(from the Kaspersky Anti-Virus Personal / Personal Pro 4.5  USER GUIDE) ...The extracting tool...can also deal with some versions of immunizers, programs protecting executable files from viruses by attaching checking code blocks (CPAV and F-XLOCK) and enciphering programs (CryptCOM) to them.

I guess this (virus-like behaviour of CPAV.EXE) sheds some light on why Avast! 4 detects non-existent virus in CPAV.EXE It also shows that something can be done about it! ;)

The Home version does support RAR archives (and always has).
Vlk

Please, Vlk, can you confirm that Pro and Home versions use the same VPS (I mean, can detect the same virus)? I think they do but I am a little bit confused now...  ::)
Btw, what is the behavior with CAB files?

Technical, indeed, avast Home and Pro both use the same engine, same samples, same kernel.

The detection rates should therefore be the same as well.

Version 4.0 Home lacked support for CAB archives, but these were included in 4.1.

That was what I was trying to remember.  It was the CAB not RAR files the Home version used to leave out.

Thanks Vlk.  ;)
Sorry, minacross for my simple question. I just want a confirmation of this fact. Thanks for you post.  ;)

Having a forum like this is a great way to make a good product even better. Still, in version 4.1.280 the same problems I pointed out earlier in this thread, remain:

1. False positive in CPAV.EXE
2. Missed virus in PKLite packed file which other products in the market are able to detect
3. "Double detection" of two worm wariants within the same file.

I hope, you people from Alwil, will fix those and other problems in an upcoming release.  :)

asafdem: I'm not sure if the detection of two variants within a single file will be "fixed". It is easily possible that a file is infected by a virus, then packed, and then infected by another virus. So, in general it's correct to announce both (all) the infections.

Thanks igor... A file double infected... I have never thought on this before...
Maybe is because I have no virus on my computer since a very long time  ::)
