 Posted: Tue Jan 23, 2007 9:24 pm Post subject: clean "servedby.advertising.com" tied to i.e. 7 |
|
|
If anyone can help: when I connect to imdb to look up something (i.e. a movie title) and then trying to get back to the first page of imdb, two "servedby.advertising.com" linked pages get between the current and the original page. So, I need three "back" clicks to return to imdb's home page.
Does anyone know how to clean my ie7 from this very annoying spyware?
Thanks in advance!
P.S. I have xp sp2 with norton internet security 5 antivirus. Full antivirus scans (updated) cannot find this spyware.

I had this exact same problem and found this thread by doing a Google search. Before I posted my hijackthis logs I went through the steps outlined here - virus scans, malware scans using 5 different products, cclean, etc. When I was ready to post my logs I found out the real problem and solution. I will post it here in case others seeing the same problem in IE7 find this thread via Google.
It is NOT spyware/malware in my case nor is it likely in user Joe Back's case. It is a bug in IE7!
I would bet you are running a hosts file full of entries from ad and bad sites set to resolve to localhost. In the file you have entries like this:
127.0.0.1 servedby.advertising.com
This keeps IE from displaying ads from this site and it worked fine in IE6 and does block the ads in IE7 - but the bug in IE7 causes it to hose up your back (previous page) function. You visit a page, like the main Amazon or imdb pages that have ads on them. You click onto a different page that has and ad or ads on it, the hosts file prevents the ad from displaying but IE7 inserts the URL you block into the browser previous page history. If there are 2 ads from the same place on the page you click on it will insert 2 bad records in the history. When you click back you don't go back, you go to the bad reference so nothing happens. Depending on the number of blocked ads it may take several clicks to get back to the actual previous page.
The fix:
Comment out or remove the entry in the hosts file for the problematic URLs and the problem goes away. Simple as that - just insert a # in column one of that line and save the changes, go back to imdb or Amazon or wherever and click around and the bad previous page bug vanishes. Of course, the pages will likely load slower and you will see the ads now.
To block the ads in a way that does not expose the IE7 bug, just add the URLs of the ad sites to the restricted sites list. Go to Internet options, security tab, click on restricted sites, then the sites button and add the URL (e.g. servedby.advertising.com) and save the changes. Exit and restart IE7 and re-do the test. The web pages should once again load faster and no ads from the sites you added should appear - and the back button once again works as it should.
I have seen this with a couple of other sites I had in my hosts file, it just depends on what page you are on and where they are pulling the ads. So when you see the bad page in your previous page history - or find you backup button did not work the first time - get the URL and check to see if it is in your hosts file and remove it and add it to your restricted sites list if you want to.
I hope this saves others lots of time and trouble. I scanned and scanned, and booted into safe mode and unloaded/uninstalled programs and found nothing wrong and nothing showed as spy or mal ware. Now I know the problem and the fix
