I-Worm.Totilix

Description I-Worm.Totilix

This is a very dangerous Internet worm spreading in e-mail messages. Upon being run on a machine, it overwrites all EXE files in the Windows directory with its copy, except EMM386.EXE, SETVER.EXE and files that are currently run and are locked (EXPLORER.EXE for instance).
The worm then registers its file to be run upon each Windows startup (this is all for nothing, because the system will not be functional anyway after all EXE files have been overwritten). While registering, the worm creates a new auto-run key in the system registry:
HKLMSoftwareMicrosoftWindowsCurrentVersionRun
RunAVUpdate = "worm filename"
where "worm filename" is the actual file name the worm has run from.
The worm also creates an "identification" registry key:
HKLMSoftwareMicrosoftAVUpdteInstall
that reports the system has already been infected and there is no need to overwrite EXE files in Windows and send infected messages.
Spreading
The worm does not obtain a victim's e-mail addres from the MS Outlook address book or from other files as other e-mail worms do, but forces a user to select a victim address. When starting, the worm displays a fake message:
AV Intelligent Updater
Please select email address to send at your friend
Select email address with 'a' only not with 'A'
[OK]
The worm then activates an e-mail client by using MAPI functions (i.e., not depending on the e-mail client brand and version), activates the Address Book menu and waits for the user to select address(es) there. The worm then sends an infected message to a selected address. The message has:
Subject: Virus Alert Update: New VBS.LoveLetter Threat
Text:
Hi Friend,
This mail contains a new AV intelligent updater for all antivirus.
To install it, execute the attachment file
if you have any problem, send mail at antivirus@hotmail.com

The attached file name is the same as the name of the file the worm has been activated from. Initially, the worm was received under the AVUPDATE.EXE name.
In case any error occurs while selecting an address or sending, the worm erases all files in the Windows directory, and displays one of the following "error" messages:
The recipient requested has not been or could not be resolved to a unique address list entry
The recipient could not be resolved to any address.The
recipient might not exist or might be unknown
One or more unspecified errors occured
The name was not resolved
There was insufficient memory to proceed
The operation was not supported by the messaging system
The user was cancelled one or more dialog box
In case the worm successfully sends infected e-mail, it disguises itself with the message:
AV Intelligent Updater
Internal error occured when you have launch this program
Contact antivirus@hotmail.com or others AV
Other Manifestations
Depending on system date and time, the worm erases files in the Windows directory and displays the following messages:

Crocodiles.1592

Description Crocodiles.1592

It is a very dangerous memory resident parasitic virus. While executing an infected program the virus searches for the COMSPEC string, and infects the command interpreter (COMMAND.COM). While executing an infected command interpreter the virus hooks INT 21h and then writes itself to the end of COM and EXE files (except SCAN.EXE) that are executed.
Depending on its generation the virus also hooks INT 8 (timer) and manifests itself with some sound effect. The virus also calls some other effects and erases the disk sectors, but that code is corrupted, and the computer halts. The virus contains the text string:
CROCODILES

Crooked.979

Description Crooked.979

It's a not memory resident not dangerous virus. It searches for a COM- and EXE-files and infects them. EXE-files are infected by a standard way, the COM-files infected into the beginning. This virus contains the encrypted string: "*.com *.exe Only God knows!". Sometimes it decrypts and types:
There was a crooked man, and he went a crooked mile,
He found a crooked sixpence against a crooked stile,
He bought a crooked cat, which caught a crooked mouse,
And they all lived together in a little crooked house.
