Excellent question. I had been tempted just to leave the bloody thing switched on as it didn't affect my surfing too much, but if it's turning every Google results page into a 4MB monster then I too would like to know where that bandwidth is coming from!
Is the client using local bandwidth to grab the page source of every hit for analysis? Seems likely as I can't see AVG taking on that amount of bandwidth - especially for a piece of software which, by Grisoft's own reckoning, is installed on over 40m PCs. Even if all those machines were used to make just one search request a
week (and found what they wanted on the first page of results) that'd be a hell of a lot of data to take on.

Well, the problem is that it indeed takes a hell of a time before the entire google page is loaded.
I tried wireshark and looked if I could figure out what is happening.
I captured everything happening between the start of the google question and the end of the pageload.
It is remarkable that every IP of the website which is in the google result is accessed and the contents of every page is in the packets.
I think that AVG downloads all pages from the google search results and scans them. When that is finished the scan results are inserted in the google page.
That would explain the bandwidth, the packets and the functionality. And AVG themselves don't have to pay for the bandwidth.
I wonder what is happening to the page visit statistics from web pages ... ... ...

Heh, that's nice. AV software with built-in DDoS attack.

True, but you can click away at any time. It doesn't slow the initial display of the actual results - thank god - it just takes forever to add a whole load of animated bloat to the original page.
Uninformed users will see this whole gimmick as a real benefit and be lulled into an even greater sense of false security. Education 0 Ignorance 1

And a very good reason for those of us in countries that charge via bandwidth used to turn off the feature and live with the stupid red x in the task bar, or switch to avast.
Bandwidth is not free, I get charged for uploads and downloads.

I've turned it off and permanently hidden the AVG systray icon to get rid of the red "!". If any
real error condition occurs (like a failed update) the new tray message "feature" will tell me.

Here's another free one, I've heard is pretty good. Never have used it yet as I'm still using AVG.

Thanks for taking the time to look into it. In a way scanning the result content is a reliable way to check of there are any obvious dangers at the target website, but AVG might not be able to follow complex redirects or other non-obvious attack paths, so the whole point is kind of moot. Anyway it cannot download _everything_ from the target website as it might quite easily contain tens of megabytes of data.
Using that kind of bandwidth just to show ok/not ok tags next to search results is intolerable. I'll certainly switch to another virus scanner when the support for 7.5 ends.

Hello melton,
The new AVG 8.0 function that does this scanning is an option that can be omitted. Refer to the Tweaking Companion on the Tweak Guides site for info on configuring AVG for unobtrusive operation.

Yes, it can be omitted but if the program then shows an error state in the tray icon it is still annoying, even though tray icons can be hidden. Overall the free AV "market" is decent nowadays: there is no need to stick with AVG if they downgrade their product so that it becomes annoying.
I for one tend to back away from products that try to overstep their main competence boundaries. As an aside integrated firewall+AV+whatever programs all tend to be more or less horrible, I've seen enough otherwise clean systems screwed up by Norton/F-Secure software to avoid them.

If you run the setup program with the switches "/REMOVE_FEATURE fea_AVG_SafeSurf /REMOVE_FEATURE fea_AVG_SafeSearch" it won't be installed at all, and you'll have an uncorrupted tray icon.
Still annoying that it should be necessary though...

I use AVG Free v7.5 on WinXP Pro, with only the avgamsvr.exe service running (control center disabled). Don't really need an AV program, but since others sometimes uses my system I want some kind of basic protection. Run this way I find it very easy on the system, it's not worthless bloat like for example NAV.

Thank you for that post - I will definitely make use of those switches!

That last theory sounds good....... but only if you are the only person using the computer. I installed and ran AVG 7.5 on a guy's computer recently.....was running real slow, with many problems. The program found 32 different virus infections. Too bad for him....too late. Had to reinstall the OS...
He has three teenage daughters....

Common sense is all well and good, and should definitely be the first line of defence, but we're none of us infallible and in possession of total concentration at all times (at least I'm not). A decent AV just provides a safety net for those occasions when you might not be 100% on top of the game, and accidentally or thoughtlessly click on something you shouldn't (easily done, maybe not even realising what's happened until much later when it's too late).
Apart from that, as exploits and malware keep getting more sophisticated, even the most clued-up of web users won't always recognise what represents a threat and what doesn't. The whole attitude of "I know what I'm doing, I don't need an AV, I've never had a virus, it'll never happen to me" seems a bit complacent IMHO...

they already have in the free version.
also tweakable from setup is the email scanning - no windows machine of mine will be downloading email so I was glad I could turn that off.
There's also a couple of files that if you rename them the annoying advert "information tab" will not appear. Rename 'avgmwdef_us.mht' and 'avgresf.dll' in the AVG program folder by adding something to the end of each - I renamed mine to .ANNOYING which seemed appropriate and easy to find if I want to reverse the procedure.
