Hi to all,
I am new one to this forum. Our sites has been attacked by some viruses. Those files are in the extension of "20090307ycbak" followed by original file. For example if our site contains a html file in the name of index.html; that virus will create a another file like "index.html 20090307ycbak". So how to rectify this problem. Can any one suggest me how to secure our websites...
