Scanning website for virus/malware

[Resler]

Does anyone know of a free program or online service that will scan a website for viruses/malware? Google isn't helping me find anything, and I'm usually good at using the right search terms.

A little background on this for those who want to know why I'm asking this. The site in question is a website run by a chem teacher at my school who uses his site to host resources for his students. He has had some trouble in the past with obvious site infections (index page would redirect to fake viagra site) and when that happened he deleted everything off his site and rewrote all the script himself. Today it came across my mind to check the site with Google's Safe Browsing Diagnostic.

Part of the report was
What happened when Google visited this site?

Of the 25 pages we tested on the site over the past 90 days, 3 page(s) resulted in malicious software being downloaded and installed without user consent. The last time Google visited this site was on 2009-03-10, and the last time suspicious content was found on this site was on 2009-03-10.

Malicious software includes 11 trojan(s), 9 scripting exploit(s), 4 adware(s). Successful infection resulted in an average of 21 new processes on the target machine.

I've already contacted him and let him know about this. I also know his site is hosted through Yahoo so I'm wondering if a big name like this would offer some sort of scanner for their customers.

I don't think there is a scanner. Many hosts will actually clean files that are regularly infected with things (like index files) by request.

This won't help now, but it works with PHP based software.

I haven't tried it, but I've used other creations by the webmaster of that site. It's encoded, but you get support.

I would probably just suggest plunking down the $10 or so for a domain, then use Freehostia. Aside from the site getting cracked, that's pretty safe.

There are a free programs that can help 1st thing you can do is use opendns it blocks many malware sites.

Then there are host managers that prevent you from going to really bad sites or getting banners that are from these bad sites.

For added security i would install Threatfire it also blocks really bad malware from getting into your machine.

I user open DNS.org which is great also you can use McAfee SiteAdvisor which will have colored icons representing good site, bad, so so etc. The site advisor is an IE addon

Site advisor is also an addon for FireFox
WOT is very similar

Avast! Antivirus scans web pages as they load. It gives a malacious warning and asks if you would like to leave the page.
