security - social.png upload viruses as images in php -

i know fact there trojan or malware in php represents image. , know filter out file upload use extensions such .txt or .png.

is there way scan files manually when being uploaded server using server built-in antivirus or server doing kind of tasks automatically us? ( mean particularly in cpanel )

thanks

if worried code being uploaded server in form of image, re-encode image upon upload. file containing code image extension throw error when encoder tries process it.
