Действительно не в тему...да и обсуждалось уже...

QUOTE
A newly-uncovered worm called W32.Deletemusic does exactly what its name impliesit goes through a PC and deletes all MP3 files in sight. And that's it. Simultaneously low-threat and highly annoying, the worm makes its way from computer to computer by spreading itself onto all attached drives of a given PC, including flash drives and removable media. If that media is then removed and inserted into another computer, it continues its music-eating rampage on the new host.
The worm then copies itself as the following file to all drives, including removable devices:
[DRIVE LETTER]:\csrss.exe
It also creates the following file so that it executes whenever a drive is accessed:
[DRIVE LETTER]:\autorun.inf
Next, the worm creates the following registry entry so that it executes whenever Windows starts:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce\"Worms" = "C:\WINDOWS\system32\logon.bat"
It also creates the following registry entries, which affect security settings:
HKEY_ALL_USERS\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\"NoFolderOptions" = "1"
HKEY_ALL_USERS\Software\Microsoft\Windows\CurrentVersion\Policies\System\"DisableTaskMgr" = "1"
The worm is designed specifically to delete all .mp3 files on all drives.
Recommendations
Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":
* Turn off and remove unneeded services. By default, many operating systems install auxiliary services that are not critical, such as an FTP server, telnet, and a Web server. These services are avenues of attack. If they are removed, blended threats have less avenues of attack and you have fewer services to maintain through patch updates.
* If a blended threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
* Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services (for example, all Windows-based computers should have the current Service Pack installed.). Additionally, please apply any security updates that are mentioned in this writeup, in trusted Security Bulletins, or on vendor Web sites.
* Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
* Configure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files.
* Isolate infected computers quickly to prevent further compromising your organization. Perform a forensic analysis and restore the computers using trusted media.
* Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
