Hi,
A web host client has had complaints that his website is infexted with some kind of virus. At this stage we don't even know if the complaint is about at trojan or some other vermin.

Is there any program that can be run from a remote location which tests a website for such infections? sort of a NAV for websites?

Thanks for any help.

All programs will have to run locally - and be installed locally to run. Unless you have the AV installed on your machine, map the remote drive and run the scan. Probably really slow if it's a large machine, and not on the same (fast) network.

The "other machine" is a client's website which is hosted 800 k's from my office. I need to know if there is a way of determining whether his website has been infected by some means, and if so, what the infection is. I don't think re-mapping is the answer here?

Regards,
Bruiser

rinse, wash, and re rinse, and wash, and repeat.

my guess probably the infected files got uploaded to the site, and are linked in the webpages... best to remove all files, check through each file that will be uploaded at the development environment, scan with antivirus. then upload fresh new copy

That's the most appropriate course of action. If you don't have an AV already installed, then assume the whole machine is compromised and simply start from the scratch, reloading OS and all files - and any database from the last backup, unless you can create a reliable database backup before starting the process.

Some worms (mainly in PHPBB forums apparently) can insert themselves into the code and then replicate from there.

Cleaning this may cost more in terms of time than simply recreating the servers.
