This has already been reported in the Wilder's security forum, but I thought I would post here as well in case the developers don't follow posts there. Several users have reported slow downs in the ability to watch youtube videos with the web scanning enabled in F-Secure 2010 AV. I have had to disable the web scanning option in order to make youtube usable.
I have also noticed when using a 3rd party downloader with Flashgot in Firefox that having web scanning turned on causes every file that I download to be downloaded twice. Is there any consideration to programming in the ability to set a file size limit for the web scanner? This way these larger downloads wouldn't be slowed down or duplicated and the realtime scanner would handle making sure they are clean. Just my thoughts to improve what is shaping up to be the killer antivirus product of 2010!

Same issue here on all computers with trials of F-Secure 2010.
Plus a couple of stalled full scans.
As the youtube issue hasn't been fixed, or by the looks of it even addressed, despite 2 months going by, I guess it's time to give up.
Such a shame, great product otherwise.

| LOL, I came to the forum looking for this particular issue and immediately saw this thread; just upgraded my 2008 version to 2010 since the license had run out and not only is youtube unusable but FireFox now seems to render itself unable to reach anything after a few hours of use and I have to kill it via task manager.

| Since posting this, I decided to turn off web scanning. I wonder if this is part of the reason it is disabled by default. The shame is that I purchased a two year license due to the fact that F-Secure is the only AV vendor I have found that doesn't use a proxy to scan web traffic. I had narrowed down my choices to this (so I could have web scanning) or Avira free (and go without a web scanner). At this point, it is looking like I should have gone the path of no web scanning and saved some money, but I'm hopeful that the developers will continue to improve this part of F-Secure so that I can enable it again.

| IIRC it's not just the 2010 version... Previous versions behaved like this with the HTTP scanner on when watching streaming video.l

Just spent $74 on a license. Now youtube is unusable!
I turned off web scanning, but... what's the use of internet security when it's turned off? I'll probably return the license and demand my money back.

I ask for solving a problem. It is irritating.

Hello,
Web traffic scanning caches the data, scans it and then releases it to the browser. Therefore it is normal that content such as youtube videos or other flash content starts delayed.
You can safely disable web traffic scanning (which is the default value).
There is no security risk involved.
In the Internet Security 2010, browsing protection protects you from harmful websites and exploits.
The real-time scanning will take care of all downloaded malware, e.g. in the browsers cache.
BR,
Stephan

But this way it should not be.
It isn't possible to rule elements out flash?

Hi,
there is good reason why FS decided to leave WTS turned off. The new modules including Deepguard 2, Exploit Shield and Browser Protection bring a toally new level of security to WebBrowsing.
Most of the web-based attacks in fact create a new unique malware for each (or only a very few) users browsing to that site. The result is, that F-Secure can not know that malware, and WTS is useless, as it only scans for known malware, still it sends a request to F-Secure to get a better answer.
Only the above mentioned modules are able to suspect a binary (by behavoir monitoring) of beeing malware and send a request (Hash and local pre-evaluation result) via ORSP to F-Secure.
In both cases creating a hash means that the file needs to be completly onthe HDD befor you can create a hash.
If you want the (questionalbe) extra security from WTS, then turn it on, but then you need to accept delays.
With flash, which can be quite large you still need to download a significat part to decide if this is only video or script.
Hope that explains it a bit.

That's the reason I asked a question about the Exploit Shield and Browser Protection in this thread ( http://forum.f-secure.com/topic.asp?TOPIC_ID=10976 ). From what I can tell the Exploit Shield and Browser Protection only work with IE and Firefox correct? If I use Opera or Chrome, will I not have the extra protection that Exploit Shield and Browser Protection offer?

I am not 100% sure, but exploit shield lists some exploits that are not for IE or FF. So, I think that you still profit from ES. Browser Protection has two parts: the browser plugin and the blocking mechanism. While the plugin might not work with Opera or Chrome, F-Secure can still be configured to generally block malitious sites.
Releasenotes of Client Security 9rc say:
- Improved interoperability with Web Traffic Scanning
Web Traffic Scanning now interferes less with 3rd party applications that send or receive data over the network. Web Traffic Scanning no longer scans the traffic of all networking applications, and only the following web browsers are supported by the Web Traffic Scanning feature:
- Microsoft Internet Explorer
- Mozilla Firefox
- Google Chrome
- Opera
...
Browsing Protection is supported when using Internet Explorer 6 or newer, or Firefox 2 or newer. Other browsers are not supported at this time.
...
<I did not find a section for ES>
So in the end: Either we get a clear answer from FS or we need to find out by testing...
