Scan extensions on WebShield

[rdsu]

Hi,

How can I set the WebShield to only scan the "Default extensions set"?

Thanks

[igor]

I don't think it's possible.

[rdsu]

Can you add this feature to the next version?

[igor]

Honestly, I'm not sure if it's really needed. Why do you think it's so useful?

Because only want that avast! scans extensions that could contain some threat, and not all of them...
This will improve the speed of my browsing...

I don't think it's possible.

Why is there an option for scanning only specific extensions in WebShield then?
Maybe the only way that is missing is the definition of a standard set of extensions like in Standard Shield...
I'm not seing that imposible as you're saying. But, as you say it's not possible, can you explain the WebShield seetings?
Why do they exist, I mean, the tab Web Scanning into Web Shield settings?

I don't think so, for 2 reasons:
1. My guess is that the vast majority of the browsing consists of HTM(L), JPG, GIF; you can handle (exlude) these extensions manually, if you want. Excluding some extensions from the small rest will make negligible difference.
2. I may be wrong, but I think that the browser processes the data according to the MIME type, not according to the extension, so it may actually not be safe to exlude additional extensions.

It's possible, though you have to enter extensions on your own.
Also great range of non infectable files are excluded via MIME. See the Exceptions tab.
Videos and audio are excluded and certain yet uninfectable image formats too (like PNG and GIF).

I wasn't trying to say that it's impossible to implement such a feature, I just meant that there is no such option in WebShield settings right now; you'd have to enter the extensions manually.

I see.
Can't you post a standard, default, suggested set of settings?
I'll thank you for that

As i said, Web Shield scans everything except excluded MIME types (MIME is a web file type identifier). And excluded are only those necessary which are most often encountered on the web and are not yet known to be infectable.

So, you have to investigate that to improve or not your program...

Why should I want that Web Shield scans a text file?

In NOD32 I can configure this...

RejZor, what can we think about a text file like Vampiric said... and there are a lot of other extensions...

Seriously, how much text in plain-text format do you actually encounter on web?
And that it's so big that you don't want to scan it? None.
I use it on my webpage for descriptions of my apps and they all together weight just few KB. Even slowest dialup can handle that.
I don't see any real (or logical) reason to do that.

MIME types:
http://www.iana.org/assignments/media-types/

I apologize... you're right... the http traffic is scanned and I was confusing with Standard Shield.
Some time ago it was posted that UDP traffic cannot be scanned as the way files are transfered cannot be recognized (some fuzzy transfer I suppose). So, ok, just MIME types need to be excluded as they're clean.
