On 1 of our servers we have strange domain redirects.
A visitor to a random domain on this server randomly is redirect to a website where he is warned there is a virus on his system.
First we suspected that it what a user problem but we receive a lot of complains, also it is not on 1 domain but randomly on the server on a random domain. We checked the domains for strange html/php code but cannot find anything wrong. (no iframes detected etc)
Also the apache config files show nothing strange and there no strange processes running on the server.
Log files also show nothing strange.
Does someone recognize this problem and has any idea what could cause this and how to fix this?
