This script, given free of charge by aeSecure, a protection and optimization software solution for Apache websites, will scan your entire site to search for some virus 'patterns' (for performance reasons, files over 1M will be ignored).The action of the script consists in running a scan: by default no file deletion will be made so there is no risk to run it on your site.
Some considerations to understand :
The scan is superficial and by no means exhaustive; only a few signatures have been searched while hacking possibilities are very numerous,
if the script detects the presence of certain signatures (e.g. "base64_decode"). This doesn't mean that your site has been hacked. Indeed, some instructions are used in a hack (like base64_decode) but are also used in safe source code,
Results should ALWAYS be properly understood before taking any action. Ask for help on a forum e.g. if you doubt.
This script is not optimized : the scan is done file by file and can take more or less time depending on the complexity of your site.
The script author accepts no responsibility for any liability for misuse of the script or action taken by the webmaster.
