Last week we alerted you to a very serious virus threat that overtakes your address book on your personal computers and causes E-mails to be issued with the virus imbedded to anyone in your computer with an E-mail address. The virus is properly named the "Mydoom" virus and is also known as the "Hello" virus. There are now two strains of this virus: A and B. The newer B version is especially dangerous in that it blocks access to certain websites such as Microsoft, Symantec and McAfee. Without access to these sites it is impossible to remove the virus or update antivirus files. The message has the known header of either "Hello or Important," but may also appear as a message saying "Returned Mail or Undeliverable Mail." To make matters worse, it may also attach itself as a ".zip" file or other form of attachment to an otherwise harmless message. The virus has become so prevalent that it is now the lead item on Microsoft's Home Page as well as those of Symantec (Norton) and McAfee. What makes this virus especially dangerous is that it has the ability to slip by both Virus Scan programs, even if they are updated to the latest definitions.
There is a fairly simple test to determine if either strain of the virus has made its way into your computer for Windows based systems (NOTE: Apple Computer systems are not impacted by this virus):
Click on Start and then Run
In the dialogue box type in cmd and then click OK
Type in CD\ and enter
At the prompt type: dir shimgapi.dll/a/s and enter
Wait until the computer is scanned. If the results show "File not found" then you are not infected. If, however, files are listed then your computer is infected with the "a" strain of the virus
Repeat step 4, this time typing in dir ctfmon.dll/a/s and enter
Wait until the computer is scanned. If the results show "File not found" then you are not infected. If, however, files are listed then your computer is infected with the "b" strain of the virus
In the event that steps 5 and/or 7 return a result other than "File not found," then you should go to the Microsoft Website (www.microsoft.com)
And click on the Mydoom virus alert box. Click on the third Link (How to tell if a computer is infected with Mydoom A or Mydoom B) and follow the instructions on how to remove the virus from your computer.
