Hello All,
You may have a worm virus as a result of my computer sending
you back some unread email I had from you that
restated your email to me, but had the words
Take a look to the attachment at the bottom with a pif or scr attachment.
Here is info. about it:
(the information from the site above is below.)
I downloaded Norton Antivirus 2001 Pro (from symantec.com) and had to
quarantine (it would not let me repair) the infected
files. However, I think it's safe to delete those files as
well.
Let me know if I can be of further assistance. I am sorry that I did
not have antivirus protection before
and may have inadvertently passed this on to you. I hope you don't
have to spend the hours
I have had to spend on ridding myself of this virus!

W32.Badtrans.13312@mm
W32.Badtrans.13312@mm is a MAPI worm that replies to all unread mails in your email message folders, and drops a backdoor Trojan. Also Known As: W32/Badtrans-A, W32/Badtrans@MM, BadTrans, IWorm_Badtrans, I-Worm.Badtrans, TROJ_BADTRANS.A Category: Worm Infection Length: 13312 Virus Definitions: April 11, 2001
When the worm is executed, it drops the backdoor Trojan Hkk32.exe in the

folder as inetd.exe, adds a run= line to the Win.ini, and displays the following
message:

To edit the registry: CAUTION: We strongly recommend that you back up the system registry before making any changes. Incorrect changes to the registry could result in permanent data loss or corrupted files. Please make sure you modify only the keys specified.

2. Type regedit and then click OK. The Registry Editor opens. 3. Navigate to the following subkey: HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\RunOnce 4. In the right pane, delete the following value: Kernel32 KERN32.EXE 5. Click Registry and then click Exit to save the changes. 6. Do one of the following: HKEY_CURRENT_USER\Software\Microsoft\ Windows NT\CurrentVersion\Windows 8. In the right pane, delete the following value: run <path>\Inetd.exe 9. Exit the Registry editor.

Save your changes and exit the System Configuration Editor. MORE INFORMATION and INSTRUCTIONS FROM THE PERSON WHO SENT ME THE
VIRUS:
This mass mailing worm attempts to send itself using Microsoft Outlook by replying to unread email messages. It also drops a remote access trojan (detected as Backdoor-NK.svr with the 4134 DATs; detected heuristically as New Backdoor prior to the 4134 DAT release). When run, the worm displays a message box entitled, "Install error" which reads, "File data corrupt: probably due to a bad data transmission or bad disk access." A copy is saved into the WINDOWS directory as INETD.EXE and an entry is entered into the WIN.INI file to run INETD.EXE at startup. KERN32.EXE (a backdoor trojan), and HKSDLL.DLL (a valid keylogger DLL) are written to the WINDOWS SYSTEM directory, and a registry entry is created to load the trojan upon system startup. How to fix: delete kern32.exe in windows\system delete HKSDLL.DLL in windows\system delete inetd.exe in windows Be sure to scan again with a virus checker to be sure you got it all. Once running, the trojan attempts to mail the victim's IP Address to the author. Once this information is obtained, the author can connect to the infected system via the Internet and steal personal information such as usernames, and passwords. In addition, the trojan also contains a keylogger program which is capable of capturing other vital information such as credit card and bank account numbers and passwords. The next time Windows is loaded, the worm attempts to email itself by replying to unread messages in Microsoft Outlook folders. The worm will be attached to these messages using one of the following filenames (note that some of these filenames are also associated with other threats, such as W95/MTX.gen@M): Card.pif The message body may contain the text: |
