kvarnerexpress 0 Report post Posted November 30, 2005 This is not a request for help...just a friendly warning to all...I'm designing a website for a fellow. He went to look at the home page I had made and the top image (you could call it the header) did not display. It displayed for him on another computer and it displayed on my computer. And all other images were displaying. The path was right. Everything was fine...as far as I could see.So, I had him "view source"...the <img> element was completely gone in the HTML document!!!!He tried viewing the document with Nortons turned off. He could see it and the <img> element was in the code. Norton's was actually deleting it.The problem? My <img> had an id="banner"...I changed all words containing "banner" from the document and replaced them with "topPic" (who cares what I call it, right?) I guess Norton's looks for keywords or something.Probably common knowledge for most, but not for me. Be careful what you name your elements and images.

jlhaslip 4 Report post Posted November 30, 2005 (edited) That's interesting.I often use id="hdr" on my sites. I wonder if it would delete an entire div id="banner"?I don't have Norton's to check that with, so would you mind doing that for us and report back?Is anyone aware of any other "reserved" words like this?

electriic ink 1 Report post Posted November 30, 2005 He probably has norton ad-blocking on and has configuired it to block all tags with certain words in. Amongst those would probably be banners, ad, ads or anything which would suggest an advertisement of some sort.It's all manually configurable so each set of strings would differ between users.I stopped using its ad-blocking ages ago. It was too difficult to ad new banner ad strings and nearly always blocked useful pictures. It also added javascript code to html documents. Share this post Link to post Share on other sites
rvalkass 5 Report post Posted November 30, 2005 I have Norton Firewall and I checked all the info out. It blocks anything which has a vaguely advert-related term in it, but only on what it classifies as uncertified sites. There are options to allow certain sites through, but its not really a good idea to get all visitors with Norton to do that :PJust another something for webmasters to think about when designing sites.

Sprnknwn 0 Report post Posted November 30, 2005 Thanks for reviewing this problem. I didn?t know about it but Norton is a very used antivirus so its good to be aware of those things. If "banner" is, I suppose there are other blocked words, like maybe "popup" or "spyware"... Share this post Link to post Share on other sites
beeseven 0 Report post Posted December 1, 2005 It'd be kind of funny if someone decided to call some random, harmless thing that: <div class="popup">Welcome to my site! Navigation is on the left... Share this post Link to post Share on other sites
Lozbo 0 Report post Posted December 1, 2005 But the problem won't fix by us having our norton configured, becouse most users dont know how to do it.A few months ago i had a problem like that and it was that dame norton thing which caused the trouble, i figure it out but didnt know why, til now... and take a look at my code: <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="460" height="93"><param name="movie" value="bannerx3.swf"><param name="quality" value="high"><embed src="bannerx3.swf" quality="high" pluginspage="https://get.adobe.com/flashplayer/otherversions/; type="application/x-shockwave-flash" width="460" height="93"></embed></object> The only thing that was messing was the actual name of the swf file... I think that norton should take a note about this, becouse most users dont know what to do about this, so it should be better if this feature would be 'hidden' but for the advanced settings for someone to hide, I'm not sure where its set as deffault but ...Thanks for sharing this issue!
