How can I test malware in website

[john1234]

Hi,

I am trying to buy one website( in PHP & MYSQL -> creates Business cards).

But Now I came to know that the website was attacked by MALWARE last year.

Now I am little worried about why and how threats appeared in website.

Could you please suggest me how can I test the Malware status in this web-software.

I am worried if the malware script is still there in some files as hidden.

I would like test everything before i buy.

Plese suggest me the tools and techniques that i need to apply malware testng and other technical testing.

Your help and suggestions would be great. Specailly would be great If i could get technique to test malware threats/script around the PHP files.

 

Thank you.

John, CT
