Can someone state the difference in protection/difference in technique between NOD32’s Web Scanner (IMON) and Avast’s WebShield?
As far I know… they’re equivalent: http traffic scanning using a local proxy (the scanner). 
Well, I’ve tested NOD32 a long time ago…
No, they aren’t equivalent. Web Shield is WAY faster and has WAY less problems than IMON.
IMON is a WinSock LSP (Layered Service Provider) while WebShield uses a different architecture (a combination of a kernel-mode TDI filter driver + a user mode scannning service).
LSP’s traditionally tend to have many issues, especially compatibility related issues. Our technology is quite unique (I’m not aware of any other product using a similar trick) and is quite problem-free…
Sorry… wrong guesses… :-[
quite problem-free=almost

Hey I’m very interested now! 
Well then can you tell me what is the difference between avast webshield and kaspersky’s Web-antivirus ???
I would say RejZoR’s comment followed by Vlk’s covers it, we think ours is better ;D
I think (but am not sure) that the web scanner in KAV 6 is quite similar to avast’s webshield. I don’t know if it has the “intelligent stream scan” feature though which makes browing with avast WebShield quite fast…
What are you keeping to avast 5 version? ;D
