illegal Charater Error - Ads not showing-up
illegal Charater Error - Adsense Ads not showing-up

Hey all,

not sure if anyone else is having this problem, but i'm getting a 'illegal character GIF89...' error in FF (also in IE - they just dont show up - no errors reported) when i visit sites (including my own) that have adsense ads on them. The ads just don't show up.

The file generating the error is the AdSense show-ads.js file. Anyone else experiencing this?

I recently wiped my computer and am pretty sure that thats not the problem - configuration, but wanted to narrow down the search for answers.

Nope. Ads look fine in IE7.

hmmm...thats weird...

i was reading a few other threads about spyware/malware replacing adsense ads with other items, but checked it out and can't link that as the problem.

I also installed Kaspersky IS and not sure if thats causing it - i though it may be blocking the ads, but it's firefox thats picking up the errors, so that eliminates that possibility.

ill keep looking, but hopefully someone will be able to shed some light on this.

Ok, so i got this problem solved - related to Kaspersky Internet Security. Hopefully this post will help others when installing Kaspersky Internet Security

I found the following post: [forum.kaspersky.com...]
(if this url gets removed, i typed 'kaspersky adsense' into google and the third link in the results, at the time, went to the post in the kaspersky forums)

After going through the method outlined therein, it still didn't solve the problem by unchecking the googlesyndication.com and googleadservices.com anti-banners masks. I added the two domains previously mentioned to the whitelist, restarted my browser (FF) and voila - they were back.

Again, hopefully this helps someone else out in the future.

Maybe its your anti virus? Are you using by any chance Norton Internet Security?
