Change your FTP password, remove the script at the bottom of the page that runs the iframe:

<script language="JavaScript">
e = '0x00' + '22';str1 = "%99%C1%CA%
blah blah blah
</script>
[/code]

You might have your host run a check to see what other files were modified at the same time. Pattern to look for is:

Login, Get File, Put File, Get File, Put File, Logout

usually no failed password attempts.

Sources for your password leak: People that have installed software for you in the past, anyone that has had FTP access to your machine, possibly any keylogger on your system.

When you give out passwords to people to install software or fix something on your site, set a temporary password, let them do the work, reset the password when they are done. Don't use the same password everywhere. Tommy keeps a black book of his passwords for each different site and sponsor login so that any one that is compromised won't be a security problem for other sites.

Thank´s. i already contacted webair to have a look at it. It seems to be a password which I used at sponsor programs and missed to change.

Could this trojan be responsible for dropping sales? My sales crashed at the beginning of May and I didn´t figure out why.
