JPEG scanning
« on: February 21, 2005, 03:31:58 PM »
The standard settings of the Web shield scans JPEG images. I guess that's due to something you could add to them that chrashed Windows and exploited a bug to execute code (isn't this fixed in newer IE and XP SP2). Have anyone tested how much this slows down loading a web-page with lots of images (like a photo albub on the net). An is there need to scan JPEG if one have newest IE6 and XP SP2 installed?

AFAIK there's currently only 1 JPG exploit ItW. So if your system is patched against it, putting image/jpg to the list of excluded content-types shouldn't hurt.

Of course, our default settings are designed to protect even those who don't have the patches properly installed.

About the speed - I'd say that unless your connection is really really fast (100mbit+), no slowdowns should be noticable. This is mainly thanks to the "Intelligent Stream Scan" feature...

thanks
