Happy news,
I deleted all the "malicious code" Or I think I deleted all of them (now the site runs clean). Now I need some help in safeguarding the codes. and with your expert advice, I have planned to
1. Checksum method
2. make the user input files a bit more stronger
for which Ill need your help.
Is this enough to make my site secure? What are your suggestions?
