Malicious code injection on web sites is a huge problem on the Internet today. We are seeing more and more web sites every day that are infected with malicious code and viruses. You could have a virus installed on your web site without even knowing about it. In order to keep your web site safe you need to monitor the health of your web site using available tools like Google Webmaster Tools, AVG web tools, Securi SiteCheck and others.
Step 1 is to find out if your web site has a virus. You can go to Securi SiteCheck to do a scan or go to AVG Online Virus Scanner to check for malicious code, trojans and viruses. It is very common for web pages to get infected with Internet garbage. If you have a web site you need to monitor it for viruses.
Step 3 is to lock down your site. Change your FTP passwords and other site passwords. Reset the file permissions in your web hosting account. On some sites that get infected a lot, because of the software or whatever, we have made all files read only. If you need to make a web site change, change the file permissions to allow the edit, then switch it back to read only. This is a little extreme but it works.
Step 4 is to report that your web site is clean. You can setup an account with Google Webmaster Tools and AVG. If your site is blacklisted you can request review.
