Maybe also try running fiddler (www.fiddlertool.com) on the server to see if you can find out where the ads are coming from.
Cheers.

Question
Adware on IIS - inserts javascript into asp/aspx pages
I am having a nitemare of a time trying to resolve. If anyone can shed light on my situation I will be most appreciative.
Basically our stand alone webserver (windows 2000 server) has been infected with adware. all it does is inserts a single line of javascript into certain key include files through the site. of course the result of this is horriffic as the whole site appears to be affected. whilst fine if you have pop up blockers for those without this the otherwise socially acceptable retail website becomes somewhat of an offensive game of close the next filthy window before the next pops up. not pretty.
i have run all the common adware removal softwares (adaware, spy bot, and windows malicious removal) but to no avail. Additionally I have installed all and any of the patches i could find and have just now run the IIS lockdown wizard which perhaps will solve the problem.
In the meantime however 10 points to anyone who can direct me to a good server grade software for ensuring this doesn't happen again.
Regards.

Thx meverest!
I am confident its not the client as I have confirmation from at least 10 users all on different networks with a reasonable knowledge of how to protect their pc's.
document footers are not enabled either.
What is slightly odd is that after I remove the offending code it can be replaced back on any line - somewhat randomly.
I have installed fiddler and will keep an eye on things however I have a feeling that the adware is on the machine already and thus is simply just inserting the code after each time I remove it - in which case it wont be using http to operate. Other than to spread within output of IIS pages that is of course.
As for the servers useage - it is a stand alone windows 2000 server collocated in a datacentre behind hardware firewalls. Never used for console applications and only used for browsing windowsupdate.com
cheers but I need a better solution,
p.s. Breaking news : After following through with IIS lockdown and all the patches I wake up this morning only to find the adware is back... grrr.
seems like a variant of old Russian IIS hack :-)
check if you have the follwoing files in system32 directory ftpcmd.txt, agent.exe,ads.vbs.
and some fake dll in inetsrv like iis7xy.dll ---where x is a random number that appears to be between 1-3 and y is a random character or number.
if its there remove it and make sure that your server is patched with all MS hotfixes. and dont try to use IE in the live web server .check if you have installed MS04-011 patch

Hello,
are you sure that it is the server and not the client?
have you looked at the 'add footer' function in IIS - on the default documents panel - maybe something got inserted in there?
who else has admin access to IIS on that server? got local and/or network firewalls in place? what else is running on the server? does it ever get used as a console for doing other stuff like web browsing, email etc?
cheers.
