Can you please explain to me, how Network Shield actually catches worms like Sasser or MSBlast. And if it blocks them or just logs their behavior?

Basically it's a very lightweight firewall (or more accurately, IDS) that scans all network traffic for signatures of known malware (namely Internet worms).
If it detects such an attack, it blocks it (by closing the hostile connection) - of course.
I think some of the competitive AV packages also offer such a feature - for example the new NAV 2005.

So,does Network Shield rely on signatures (VPS) or it uses "generic" blocking.
I know NAV2005 Worm Blocker uses generic rules,probably avast! does the same. At least i don't have any compatibility problems with Network Shield and eMule
(NAV WormBlocker hates eMule)

It uses signatures. No generics/heuristics. That would probably be too risky (slow, and problem-prone) anyway...

Ok,the last question
Do i get any popup when certain attack happens (which is detected by Network Shield)? Something like popup window for updates or normal virus detected warning?

Yes, you get a popup similar to the one which is displayed whenever a virus is detected.
(Not the dialog - the red/yellow on-access scanner message in the notification area of the screen, if you know what I mean).
