I am looking for somebody with experience in protecting a website from being infected with a trojan. This is an Oscommerce site that keeps getting it's google redirect manipulated. This is the second time this has happend. The site is fine when you enter it direct, but when you wnter it from google it redirects to a page that wants to download a trojan.
I want sombody to fix the redirect problem and look to the saftey of the site, whether we need to change the online forms or to look at other ways people are getting through the back door.
