1. Update to the latest database of virus signatures of your Antivirus and Anti-Malware software.
2. Scan the PC for viruses and Malware.
3. Check for the latest OS updates (e.g. Windows).
4. Check for the latest updates of your browser (e.g. Internet Explorer / Firefox).
5. Update Adobe Flash player to the latest available version as vulnerabilities were found in it (check http://get.adobe.com/flashplayer/ for more information)
6. Some viruses cloak themselves from your currently installed Antiviruses, therefore we also recommend to use a different program to scan thePC (e.g. http://www.malwarebytes.org/mbam.php).
7. Delete passwords from all FTP clients and do not use the ?Save Password? feature. Update the FTP clients to the latest versions.
8. Change all your passwords (including FTP and main cPanel password). It is recommended to use the Password generators in order to make the guessing of the password extremely difficult.
9. Inspect all your .html and .php files (e.g. index.php, index.html, main.php, header.php, footer.php and so on) for the malicious code. It is usually added in the end of the file. Clean the infected files.
10. Update all installed software on your hosting accounts (e.g. Wordpress, Joomla and so on)
11. Check the permissions of your ?.htaccess? files (they should be set to 644) and of the folders, which contain the scripts you use (they
should be set to 755).
12. Make sure you scan any file with your Antivirus prior to uploading it to the server.
