Project description
Recently, a virus has been constantly poured into the site and this virus begins to copy all files indefinitely, until the server runs out of free space, and then the hosting turns off the site. Access to the site is available, so you can analyze it and remove the virus, as well! You need to close the hole in the site through which this virus is removed!
